4 Configuration and Installation Options

This chapter introduces important parts of a control file for standard purposes. To learn about other available options, use the configuration management system.

Note that for some configuration options to work, additional packages need to be installed, depending on the software selection you have configured. If you choose to install a minimal system then some packages might be missing and need to be added to the individual package selection.

YaST will install packages required in the second phase of the installation and before the post-installation phase of AutoYaST has started. However, if necessary YaST modules are not available in the system, important configuration steps will be skipped. For example, no security settings will be configured if yast2-security is not installed.

4.1 General Options

The general section includes all settings that influence the installation workflow. The overall structure of this section looks like the following:

<?xml version="1.0"?>

<profile>

4.1.1 The Mode Section

The mode section configures the behavior of AutoYaST with regard to user confirmations and rebooting. The following elements are allowed in the mode section:

activate_systemd_default_target

If you set this entry to false, the default systemd target will not be activated via the call systemctl isolate. Setting this value is optional. The default is true.

<general>
 <mode>
  <activate_systemd_default_target config:type="boolean">
   true
  </activate_systemd_default_target>
 </mode>
 ...
</general>
confirm

By default, the installation stops at the Installation Settings screen. Up to this point, no changes have been made to the system and settings may be changed on this screen. To proceed and finally start the installation, the user needs to confirm the settings. By setting this value to false the settings are automatically accepted and the installation starts. Only set to false if you want to carry out a fully unattended installation. Setting this value is optional. The default is true.

<general>
 <mode>
  <confirm config:type="boolean">true</confirm>
 </mode>
 ...
</general>
confirm_base_product_license

If you set this to true, the EULA of the base product will be shown. The user needs to accept this license. Otherwise the installation will be canceled. Setting this value is optional. The default is false. This setting applies to the base product license only. Use the flag confirm_license in the add-on section for additional licenses (see Section 4.9.2, “Installing Additional/Customized Packages or Products” for details).

<general>
 <mode>
  <confirm_base_product_license config:type="boolean">
   false
  </confirm_base_product_license>
 </mode>
 ...
</general>
final_halt

If you set this to true, the machine will shut down at the very end of the installation (when everything is installed and configured at the end of the second stage). Setting this value is optional. The default is true. It makes no sense to set both this and final_reboot to true.

<general>
 <mode>
  <final_halt config:type="boolean">true</final_halt>
 </mode>
 ...
</general>
final_reboot

If you set this to true, the machine will reboot at the end of the installation (when everything is installed and configured at the end of the second stage). Setting this value is optional. The default is true. It makes no sense to set both this and final_halt to true.

<general>
 <mode>
  <final_reboot config:type="boolean">true</final_reboot>
 </mode>
 ...
</general>
final_restart_services

If you set this entry to false, services will not be restarted at the end of the installation (when everything is installed and configured at the end of the second stage). Setting this value is optional. The default is true.

<general>
 <mode>
  <final_restart_services config:type="boolean">
   true
  </final_restart_services>
 </mode>
 ...
</general>
halt

Shuts down the machine after the first stage. All packages and the boot loader have been installed and all your chroot scripts have run. Instead of rebooting into stage two, the machine is turned off. If you turn it on again, the machine boots and the second stage of the autoinstallation starts. Setting this value is optional. The default is false.

<general>
 <mode>
  <halt config:type="boolean">false</halt>
 </mode>
 ...
</general>
max_systemd_wait

Specifies how long AutoYaST waits (in seconds) at most for systemd to set up the default target. Setting this value is optional and should not normally be required. The default is 30 (seconds).

<general>
 <mode>
  <max_systemd_wait config:type="integer">30</max_systemd_wait>
 </mode>
 ...
</general>
ntp_sync_time_before_installation

Specify the NTP server with which to synchronize time before starting the installation. Time synchronization will only occur if this option is set. Keep in mind that you need a network connection and access to a time server. Setting this value is optional. By default no time synchronization will occur.

<general>
 <mode>
  <ntp_sync_time_before_installation>
   &ntpname;
  </max_systemd_wait>
 </mode>
 ...
</general>
second_stage

A regular installation of SUSE Linux Enterprise Server is performed in a single stage. The auto-installation process, however, is divided into two stages. After the installation of the basic system the system boots into the second stage where the system configuration is done. Set this option to false to disable the second stage. Setting this value is optional. The default is true.

<general>
 <mode>
  <second_stage config:type="boolean">true</second_stage>
 </mode>
 ...
</general>

4.1.2 Configuring the Installation Settings Screen

AutoYaST allows you to configure the Installation Settings screen, which shows a summary of the installation settings. On this screen, the user can change the settings before confirming them to start the installation. Using the proposal tag, you can control which settings (proposals) are shown in the installation screen. A list of valid proposals for your products is available from the /control.xml file on the installation medium. This setting is optional. By default all configuration options will be shown.

<proposals config:type="list">
 <proposal>partitions_proposal</proposal>
 <proposal>timezone_proposal</proposal>
 <proposal>software_proposal</proposal>
</proposals>

4.1.3 The Self-Update Section

During the installation, YaST can update itself to solve bugs in the installer that were discovered after the release. Refer to the Deployment Guide for further information about this feature. Use the following tags to configure the YaST self-update:

self_update

This option enables (set to true) or disables (set to false) the YaST self-update feature. Setting this value is optional. The default is true.

<general>
 <self_update config:type="boolean">true</self_update>
 ...
</general>

Alternatively, you can specify the boot parameter self_update=1 on the kernel command line.

self_update_url

Location of the update repository to use during the YaST self-update. For more information, refer to the Deployment Guide.

Important
Important: Installer Self-Update Repository Only

The self_update_url parameter expects only the installer self-update repository URL. Do not supply any other repository URL—for example the URL of the software update repository.

<general>
 <self_update_url>
  http://example.com/updates/$arch
 </self_update_url>
 ...
</general>

The URL may contain the variable $arch. It will be replaced by the system's architecture, such as x86_64, s390x, etc.

Alternatively, you can specify the boot parameter self_update=1 together with self_update=URL on the kernel command line.

4.1.4 The Semi-Automatic Section

AutoYaST offers to start some YaST modules during the installation. This is useful if you want to give administrators installing the machine the possibility to manually configure some aspects of the installation while at the same time automating the rest of the installation. Within the semi-automatic section you can start the following YaST modules:

  • The network settings module (networking)

  • The partitioner (partitioning)

  • The registration module (scc)

The following example starts all three supported YaST modules during the installation:

<general>
 <semi-automatic config:type="list">
  <semi-automatic_entry>networking</semi-automatic_entry>
  <semi-automatic_entry>scc</semi-automatic_entry>
  <semi-automatic_entry>partitioning</semi-automatic_entry>
 </semi-automatic>
</general>

4.1.5 The Signature Handling Section

By default AutoYaST will only install signed packages from sources with known GPG keys. Use this section to overwrite the default settings.

Warning
Warning: Overwriting the Signature Handling Defaults

Installing unsigned packages, packages with failing checksum checks, or when accepting packages from sources you do not trust is a major security risk. Packages may have been modified and may install malicious software on your machine. Only overwrite the defaults in this section if you are sure the repository and the packages can be trusted. SUSE is not responsible for any problems arising from software installed with integrity checks disabled.

Default values for all options are false. If an option is set to false and a package or repository fails the respective test, it is silently ignored and will not be installed.

accept_unsigned_file

If set to true, AutoYaST will accept unsigned files like the content file.

<general>
 <signature-handling>
  <accept_unsigned_file config:type="boolean">
   false
  </accept_unsigned_file>
 <signature-handling>
 ...
<general>
accept_file_without_checksum

If set to true, AutoYaST will accept files without a checksum in the content file.

<general>
 <signature-handling>
  <accept_file_without_checksum config:type="boolean">
   false
  </accept_file_without_checksum>
 <signature-handling>
 ...
<general>
accept_verification_failed

If set to true, AutoYaST will accept signed files even when the signature verification fails.

<general>
 <signature-handling>
  <accept_verification_failed config:type="boolean">
   false
  </accept_verification_failed>
 <signature-handling>
 ...
<general>
accept_unknown_gpg_key

If set to true, AutoYaST will accept new GPG keys of the installation sources, for example the key used to sign the content file.

<general>
 <signature-handling>
  <accept_unknown_gpg_key config:type="boolean">
   false
  </accept_unknown_gpg_key>
 <signature-handling>
 ...
<general>
accept_non_trusted_gpg_key

Set this option to true to accept known keys you have not yet trusted.

<general>
 <signature-handling>
  <accept_non_trusted_gpg_key config:type="boolean">
   false
  </accept_non_trusted_gpg_key>
 <signature-handling>
 ...
<general>
import_gpg_key

If set to true, AutoYaST will accept and import new GPG keys on the installation source in its database.

<general>
 <signature-handling>
  <import_gpg_key config:type="boolean">
   false
  </import_gpg_key>
 <signature-handling>
 ...
<general>

4.1.6 The Storage Section

This section lets you enable multipath support for the installation. You may also configure the partition alignment settings here.

btrfs_set_default_subvolume_name

See Section 4.5.3, “Btrfs subvolumes” for more information.

start_multipath

When installing on a network storage that is accessed via multiple paths, you need to enable multipath for the installation by setting this parameter to true. Setting this value is optional. The default is false.

<general>
 <storage>
  <start_multipath config:type="boolean">true</start_multipath>
 <storage>
 ...
</general>

Alternatively, you can use the following parameter on the Kernel command line: LIBSTORAGE_MULTIPATH_AUTOSTART=ON

4.1.7 The Wait Section

In the second stage of the installation the system is configured by running modules, for example the network configuration. Within the wait section you can define scripts that will get executed before and after a specific module has run. You can also configure a span of time in which the system is inactive (sleeps) before and after each module.

pre-modules

Defines scripts and sleep time executed before a configuration module starts. The following code shows an example setting the sleep time to ten seconds and executing an echo command before running the network configuration module.

<general>
 <wait>
  <pre-modules config:type="list">
   <module>
    <name>networking</name>
    <sleep>
     <time config:type="integer">10</time>
     <feedback config:type="boolean">true</feedback>
    </sleep>
    <script>
     <source>echo foo</source>
     <debug config:type="boolean">false</debug>
    </script>
   </module>
  </pre-modules>
  ...
<general>
post-modules

Defines scripts and sleep time executed after a configuration module starts. The following code shows an example setting the sleep time to ten seconds and executing an echo command after running the network configuration module.

<general>
 <wait>
  <post-modules config:type="list">
   <module>
    <name>networking</name>
    <sleep>
     <time config:type="integer">10</time>
     <feedback config:type="boolean">true</feedback>
    </sleep>
    <script>
     <source>echo foo</source>
     <debug config:type="boolean">false</debug>
    </script>
   </module>
  </post-modules>
  ...
<general>

4.1.8 Blacklisting Unused Devices on IBM IBM Z

On IBM IBM Z you can prevent the kernel from looking at unused hardware devices, by running cio_ignore and blacklisting them. This is done by setting the AutoYaST parameter with the same name to true. Setting this value is optional and only applies to installations on IBM IBM Z hardware. The default is true.

<general>
 <cio_ignore config:type="boolean">true</cio_ignore>
 ...
<general>

4.1.9 Examples for the general Section

4.2 Reporting

The report resource manages three types of pop-ups that may appear during installation:

  • message pop-ups (usually non-critical, informative messages),

  • warning pop-ups (if something might go wrong),

  • error pop-ups (in case an error occurs).

Example 4.2: Reporting Behavior
<report>
  <errors>
    <show config:type="boolean">true</show>
    <timeout config:type="integer">0</timeout>
    <log config:type="boolean">true</log>
  </errors>
  <warnings>
    <show config:type="boolean">true</show>
    <timeout config:type="integer">10</timeout>
    <log config:type="boolean">true</log>
  </warnings>
  <messages>
    <show config:type="boolean">true</show>
    <timeout config:type="integer">10</timeout>
    <log config:type="boolean">true</log>
  </messages>
  <yesno_messages>
    <show config:type="boolean">true</show>
    <timeout config:type="integer">10</timeout>
    <log config:type="boolean">true</log>
  </yesno_messages>
</report>

Depending on your experience, you can skip, log and show (with timeout) those messages. It is recommended to show all messages with timeout. Warnings can be skipped in some places but should not be ignored.

The default setting in auto-installation mode is to show errors without timeout and to show all warnings/messages with a timeout of 10 seconds.

Warning
Warning: Critical System Messages

Note that not all messages during installation are controlled by the report resource. Some critical messages concerning package installation and partitioning will show up ignoring your settings in the report section. Usually those messages will need to be answered with Yes or No.

4.3 System Registration and Extension Selection

Registering the system with the can be configured within the suse_register resource. The following example registers the system with the SUSE Customer Center. In case your organization provides its own registration server, you need to specify the required data with the reg_server* properties. Refer to the table below for details.

<suse_register>
  <do_registration config:type="boolean">true</do_registration>
  <email>tux@example.com</email>
  <reg_code>MY_SECRET_REGCODE</reg_code>
  <install_updates config:type="boolean">true</install_updates>
  <slp_discovery config:type="boolean">false</slp_discovery>
</suse_register>

As an alternative to the fully automated registration, AutoYaST can also be configured to start the YaST registration module during the installation. this offers the possibility to enter the registration data manually. The following XML code is required:

<general>
 <semi-automatic config:type="list">
   <semi-automatic_entry>scc</semi-automatic_entry>
 </semi-automatic>
</general>
Tip
Tip: Using the Installation Network Settings

In case you need to use the same network settings that were used for the installation, AutoYaST needs to run the network setup in stage 1 right before the registration is started:

<networking>
  <setup_before_proposal config:type="boolean">true</setup_before_proposal>
</networking>

Element

Description

Comment

do_registration

Boolean

<do_registration config:type="boolean"
>true</do_registration>

Specify whether the system should be registered or not. If set to false all other options are ignored and the system is not registered.

e-mail

E-mail address

<email>tux@example.com</email>

Optional. The e-mail address matching the registration code.

reg_code

Text

<reg_code>SECRET_REGCODE</reg_code>

Required. Registration code.

install_updates

Boolean

<install_updates config:type="boolean"
>true</install_updates>

Optional. Determines if updates from the Updates channels should be installed. The default value is to not install them (false).

slp_discovery

Boolean

<slp_discovery config:type="boolean"
>true</slp_discovery>

Optional. Search for a registration server via SLP. The default value is false.

Expects to find a single server. If more than one server is found, the installation will fail. In case there is more than one registration server available, you need to specify one with reg_server.

If neither slp_discovery nor reg_server are set, the system is registered with the SUSE Customer Center.

This setting also affects the self-update feature: If it is disabled, no SLP search will be performed.

reg_server

URL

<reg_server>
  https://smt.example.com
</reg_server>

Optional. SMT server URL. If neither slp_discovery nor reg_server are set, the system is registered with the SUSE Customer Center.

The SMT server is queried for a URL of the self-update repository. So if self_update_url is not set, the SMT server influences where the self-updates are downloaded from. Check out the Deployment Guide to find further information about this feature.

reg_server_cert_fingerprint_type

SHA1 or SHA256

<reg_server_cert_fingerprint_type>
  SHA1
</reg_server_cert_fingerprint_type>

Optional. Requires a checksum value provided with reg_server_cert_fingerprint. Using the fingerprint is recommended, since it ensures the SSL certificate is verified. The matching certificate will be automatically imported when the SSL communication fails because of a verification error.

reg_server_cert_fingerprint

Server Certificate Fingerprint value in hexadecimal notion (case-insensitive).

<reg_server_cert_fingerprint>
  01:AB...:EF
</reg_server_cert_fingerprint>

Optional. Requires a fingerprint type value provided with reg_server_cert_fingerprint_type. Using the fingerprint is recommended, since it ensures the SSL certificate is verified. The matching certificate will be automatically imported when the SSL communication fails because of a verification error.

reg_server_cert

URL

<reg_server_cert>
  http://smt.example.com/smt.crt
</reg_server_cert>

Optional. URL of the SSL certificate on the server. Using this option is not recommended, since the certificate that is downloaded is not verified. Use reg_server_cert_fingerprint instead.

addons

Add-ons list

Specify an extension from the registration server that should be added to the installation repositories. See Section 4.3.1, “Extensions” for details.

Tip
Tip: Obtaining a Server Certificate Fingerprint

To obtain a server certificate fingerprint for use with the reg_server_cert_fingerprint entry, run the following command on the SMT server (edit the default path to the smt.crt file, if needed):

openssl x509 -noout -in /srv/www/htdocs/smt.crt -fingerprint -sha256

To retrieve a fingerprint from the SMT server, use the following command:

curl --insecure -v https://scc.suse.com/smt.crt 2> /dev/null | openssl
x509 -noout -fingerprint -sha256

Replace scc.suse.com with your server.

Note: This can be used in a trusted network only! In a non-trusted network, for example the Internet, you should get the fingerprint directly from the server by other means. Fingerprints can be fetched via SSH, a saved server configuration and other sources. Alternatively, you can verify that the downloaded certificate is exactly the same as on the server.

4.3.1 Extensions

The SUSE Customer Center provides several extensions, such as sle-sdk (SUSE Software Development Kit - SDK) that can be included as additional sources during the installation. Extensions can be added via the addons property within the suse_register block.

Note
Note: Availability of Extensions

The availability of extensions is product and architecture dependent. Not all extensions are available on other architectures. The only extension available for SUSE Linux Enterprise Desktop is the sle-sdk.

Some extensions, such as the sle-we, sle-ha and sle-ha-geo require a registration code.

With SUSEConnect --list-extensions (available since SLES 12 SP1), you can list all available extensions in a registered system. The result looks like:

Install with: SUSEConnect -p sle-sdk/12.2/x86_64

The -p argument displays the NAME/VERSION/ARCH values that can be used in the AutoYaST profile as follows:

<addons config:type="list">
 <addon>
  <!-- SUSE Linux Enterprise Software Development Kit -->
  <name>sle-sdk</name>
  <version>12.2</version>
  <arch>x86_64</arch>
 </addon>
</addons>

For background information and add-on listings for SLES 12, 12 SP1, and 12 SP2, see https://github.com/yast/yast-registration/wiki/Available-SCC-Extensions-for-Use-in-Autoyast. The listings will get updated from time to time.

4.4 The Boot Loader

This documentation is for yast2-bootloader and applies to GRUB 2. For older product versions shipping with legacy GRUB, refer to the documentation that comes with your distribution in /usr/share/doc/packages/autoyast2/

The general structure of the AutoYaST boot loader part looks like the following:

<bootloader>
  <loader_type>
    <!-- boot loader type (grub2 or grub2-efi) -->
  </loader_type>
  <global>
    <!--
      entries defining the installation settings for GRUB 2 and
      the generic boot code
    -->
  </global>
  <device_map config:type="list">
    <!-- entries defining the order of devices -->
  </device_map>
 </bootloader>

4.4.1 Loader Type

Define which boot loader to use: grub2 or grub2-efi.

<loader_type>grub2</loader_type>

4.4.2 Globals

This is an important if optional part. Define here where to install GRUB 2 and how the boot process will work. Again, yast2-bootloader proposes a configuration if you do not define one. Usually the AutoYaST control file includes only this part and all other parts are added automatically during installation by yast2-bootloader. Unless you have some special requirements, do not specify the boot loader configuration in the XML file.

<global>
  <activate config:type="boolean">true</activate>
  <timeout config:type="integer">10</timeout>
  <suse_btrfs config:type="boolean">true</suse_btrfs>
  <terminal>gfxterm</terminal>
  <gfxmode>1280x1024x24</gfxmode>
</global>

Attribute

Description

activate

Set the boot flag on the boot partition. The boot partition can be / if there is no separate /boot partition. If the boot partition is on a logical partition, the boot flag is set to the extended partition.

<activate config:type="boolean">true</activate>

append

Kernel parameters added at the end of boot entries for normal and recovery mode.

<append>nomodeset vga=0x317</append>

boot_boot

Write GRUB 2 to a separate /boot partition. If no separate /boot partition exists, GRUB 2 will be written to /.

<boot_boot>false</boot_boot>

boot_custom

Write GRUB 2 to a custom device.

<boot_custom>/dev/sda3</boot_custom>

boot_extended

Write GRUB 2 to the extended partition (important if you want to use a generic boot code and the /boot partition is logical). NOTE: if the boot partition is logical, you should use boot_mbr (write GRUB 2 to MBR) rather than generic_mbr.

<boot_extended>false</boot_extended>

boot_mbr

Write GRUB 2 to MBR of the first disk in the order (device.map includes order of disks).

<boot_mbr>false</boot_mbr>

boot_root

Write GRUB 2 to / partition.

<boot_root>false</boot_root>

generic_mbr

Write generic boot code to MBR, will be ignored if boot_mbr is set to true.

<generic_mbr config:type="boolean">false</generic_mbr>

gfxmode

Graphical resolution of the GRUB 2 screen (requires <terminal> to be set to gfxterm. Valid entries are auto, HORIZONTALxVERTICAL, or HORIZONTALxVERTICALxCOLOR DEPTH. You can see the screen resolutions supported by GRUB 2 on a particular system by using the vbeinfo command at the GRUB 2 command line in the running system.

<gfxmode>1280x1024x24</gfxmode>

os_prober

If set to true, automatically searches for operating systems already installed and generates boot entries for them during the installation

<os_prober config:type="boolean">false</os_prober>

cpu_mitigations

Allows to choose a default setting of kernel boot command line parameters for CPU mitigation (and at the same time strike a balance between security and performance). Possible values are:

auto Enables all mitigations required for your CPU model, but does not protect against cross-CPU thread attacks. This setting may impact performance to some degree, depending on the workload.

nosmt Provides the full set of available security mitigations. Enables all mitigations required for your CPU model. In addition, it disables Simultaneous Multithreading (SMT) to avoid side-channel attacks across multiple CPU threads. This setting may further impact performance, depending on the workload.

off Disables all mitigations. Side-channel attacks against your CPU are possible, depending on the CPU model. This setting has no impact on performance.

manual Does not set any mitigation level. Specify your CPU mitigations manually by using the kernel command line options.

<cpu_mitigations>auto</cpu_mitigations>

If not set in AutoYaST, the respective settings can be changed via kernel command line. By default, the (product-specific) settings in the /control.xml file on the installation medium are used (if nothing else is specified).

suse_btrfs

Obsolete and no longer used. Booting from Btrfs snapshots is automatically enabled from SLES 12 SP2 onward.

serial

Command to execute if the GRUB 2 terminal mode is set to serial.

<serial>
  serial --speed=115200 --unit=0 --word=8 --parity=no --stop=1
</serials>

terminal

Specify the GRUB 2 terminal mode to use, Valid entries are console, gfxterm, and serial. If set to serial, the serial command needs to be specified with <serial>, too.

<terminal>serial</terminal>

timeout

The timeout in seconds until the default boot entry is booted automatically.

<timeout config:type="integer">10</timeout>

trusted_boot

If set to true, then Trusted GRUB is used. Trusted GRUB supports Trusted Platform Module (TPM). Works only for grub2 bootloader.

<trusted_boot>true</trusted_boot>

vgamode

Adds the kernel parameter vga=VALUE to the boot entries.

<vgamode>0x317</vgamode>

xen-append

Kernel parameters added at the end of boot entries for Xen guests.

<append>nomodeset vga=0x317</append>

xen-kernel-append

Kernel parameters added at the end of boot entries for Xen kernels on the VM Host Server.

<xen-append>dom0_mem=768M</xen-append>

4.4.3 Device map

GRUB 2 avoids mapping problems between BIOS drives and Linux devices by using device ID strings (UUIDs) or file system labels when generating its configuration files. GRUB 2 utilities create a temporary device map on the fly, which is usually sufficient, particularly on single-disk systems. However, if you need to override the automatic device mapping mechanism, create your custom mapping in this section.

<device_map config:type="list">
  <device_map_entry>
    <firmware>hd0</firmware> <!-- order of devices in target map  -->
    <linux>/dev/disk/by-id/ata-ST3500418AS_6VM23FX0</linux> <!-- name of device (disk)  -->
  </device_map_entry>
</device_map>

4.5 Partitioning

4.5.1 Drive Configuration

The elements listed below must be placed within the following XML structure:

<profile>
  <partitioning config:type="list">
    <drive>
     ...
    </drive>
  </partitioning>
</profile>

Attribute

Values

Description

device

The device you want to configure in this <drive> section. You can use persistent device names via id, like /dev/disk/by-id/ata-WDC_WD3200AAKS-75L9A0_WD-WMAV27368122 or by-path,like /dev/disk/by-path/pci-0001:00:03.0-scsi-0:0:0:0.

<device>/dev/sda</device>

Optional. If left out, AutoYaST tries to guess the device. See Tip: Skipping Devices on how to influence guessing.

A RAID must always have /dev/md as device.

initialize

If set to true, the partition table gets wiped out before AutoYaST starts the partition calculation.

<initialize config:type="boolean">true</initialize>

Optional. The default is false.

partitions

A list of <partition> entries (see Section 4.5.2, “Partition Configuration”).

<partitions config:type="list">
  <partition>...</partition>
  ...
</partitions>

Optional. If no partitions are specified, AutoYaST will create a reasonable partitioning (see Section 4.5.6, “Automated Partitioning”).

pesize

This value only makes sense with LVM.

<pesize>8M</pesize>

Optional. Default is 4M for LVM volume groups.

use

Specifies the strategy AutoYaST will use to partition the hard disk.

Choose between:

  • all (uses the whole device while calculating the new partitioning),

  • linux (only existing Linux partitions are used),

  • free (only unused space on the device is used, no other partitions are touched),

  • 1,2,3 (a list of comma separated partition numbers to use).

This parameter should be provided.

type

Specify the type of the drive,

Choose between:

<type config:type="symbol">CT_LVM</type>

Optional. Default is CT_DISK for a normal physical hard disk.

disklabel

Describes the type of the partition table.

Choose between:

  • msdos

  • gpt

<disklabel>gpt</disklabel>

Optional. By default YaST decides what makes sense.

keep_unknown_lv

This value only makes sense for type=CT_LVM drives. If you are reusing a logical volume group and you set this to true, all existing logical volumes in that group will not be touched unless they are specified in the <partitioning> section. So you can keep existing logical volumes without specifying them.

<keep_unknown_lv config:type="boolean"
>false</keep_unknown_lv>

Optional. The default is false.

enable_snapshots

Enables snapshots on Btrfs file systems mounted at / (does not apply to other file systems, or Btrfs file systems not mounted at /).

<enable_snapshots config:type="boolean"
>false</enable_snapshots>

Optional. The default is true.

Tip
Tip: Skipping Devices

You can influence AutoYaST's device-guessing for cases where you do not specify a <device> entry on your own. Usually AutoYaST would use the first device it can find that looks reasonable but you can configure it to skip some devices like this:

<partitioning config:type="list">
  <drive>
    <initialize config:type="boolean">true</initialize>
    <skip_list config:type="list">
      <listentry>
        <!-- skip devices that use the usb-storage driver -->
        <skip_key>driver</skip_key>
        <skip_value>usb-storage</skip_value>
      </listentry>
      <listentry>
        <!-- skip devices that are smaller than 1GB -->
        <skip_key>size_k</skip_key>
        <skip_value>1048576</skip_value>
        <skip_if_less_than config:type="boolean">true</skip_if_less_than>
      </listentry>
      <listentry>
        <!-- skip devices that are larger than 100GB -->
        <skip_key>size_k</skip_key>
        <skip_value>104857600</skip_value>
        <skip_if_more_than config:type="boolean">true</skip_if_more_than>
      </listentry>
    </skip_list>
  </drive>
</partitioning>

For a list of all possible <skip_key>, run yast2 ayast_probe on an already installed system.

4.5.2 Partition Configuration

The elements listed below must be placed within the following XML structure:

<drive>
  <partitions config:type="list">
    <partition>
      ...
    </partition>
  </partitions>
</drive>

Attribute

Values

Description

create

Specify if this partition must be created or if it already exists.

<create config:type="boolean" >false</create>

If set to false, you also need to set partition_nr to tell AutoYaST the partition number.

crypt_fs

Partition will be encrypted.

<crypt_fs config:type="boolean">false</crypt_fs>

Default is false.

crypt_key

Encryption key

<crypt_key>xxxxxxxx</crypt_key>

Only needed if crypt_fs has been set to true.

mount

The mount point of this partition.

<mount>/</mount>
<mount>swap</mount>

You should have at least a root partition (/) and a swap partition.

fstopt

Mount options for this partition.

<fstopt>
  ro,noatime,user,data=ordered,acl,user_xattr
</fstopt>

See man mount for available mount options.

label

The label of the partition (useful for the mountby parameter; see below).

<label>mydata</label>

See man e2label for an example.

uuid

The UUID of the partition (only useful for the mountby parameter; see below).

<uuid
>1b4e28ba-2fa1-11d2-883f-b9a761bde3fb</uuid>

See man uuidgen.

size

The size of the partition, for example 4G, 4500M, etc. The /boot partition and the swap partition can have auto as size. Then AutoYaST calculates a reasonable size. One partition can have the value max to use all remaining space.

You can also specify the size in percentage. So 10% will use 10% of the size of the hard disk or volume group. You can mix auto, max, size, and percentage as you like.

<size>10G</size>

format

Specify if AutoYaST should format the partition.

<format config:type="boolean">false</format>

If you set create to true, then you likely want this option set to true as well.

file system

Specify the file system to use on this partition:

  • btrfs

  • ext2

  • ext3

  • ext4

  • vfat

  • xfs

  • swap

<filesystem config:type="symbol"
>ext3</filesystem>

Optional. The default is btrfs for the root partition (/) and xfs for data partitions.

mkfs_options

Specify an option string that is added to the mkfs command.

<mkfs_options>-I 128</mkfs_options>

Optional. Only use this when you know what you are doing.

partition_nr

The partition number of this partition. If you have set create=false or if you use LVM, then you can specify the partition via partition_nr. You can force AutoYaST to only create primary partitions by assigning numbers below 5.

<partition_nr config:type="integer"
>2</partition_nr>

Usually, numbers 1 to 4 are primary partitions while 5 and higher are logical partitions.

partition_id

The partition_id sets the id of the partition. If you want different identifiers than 131 for Linux partition or 130 for swap, configure them with partition_id.

<partition_id config:type="integer"
>131</partition_id>

Possible values are:

Swap: 130
Linux: 131
LVM: 142
MD RAID: 253
EFI partition: 259

The default is 131 for Linux partition and 130 for swap.

partition_type

When using an msdos partition table, this element sets the type of the partition. The value can be primary or logical. This value is ignored when using a gpt partition table, because such a distinction does not exist in that case.

<partition_type>primary</partition_type>

Optional. Allowed values are primary (default) and logical.

mountby

Instead of a partition number, you can tell AutoYaST to mount a partition by device, label, uuid, path or id, which are the udev path and udev id (see /dev/disk/...).

<mountby config:type="symbol"
>label</mountby>

See label and uuid documentation above. The default depends on YaST and usually is id.

subvolumes

List of subvolumes to create for a file system of type Btrfs. This key only makes sense for file systems of type Btrfs. See Section 4.5.3, “Btrfs subvolumes” for more information.

<subvolumes config:type="list">
  <path>tmp</path>
  <path>opt</path>
  <path>srv</path>
  <path>var/crash</path>
  <path>var/lock</path>
  <path>var/run</path>
  <path>var/tmp</path>
  <path>var/spool</path>
  ...
</subvolumes>

lv_name

If this partition is on a logical volume in a volume group, specify the logical volume name here (see the is_lvm_vg parameter in the drive configuration).

<lv_name>opt_lv</lv_name>

stripes

An integer that configures LVM striping. Specify across how many devices you want to stripe (spread data).

<stripes config:type="integer">2</stripes>

stripesize

Specify the size of each block in KB.

<stripesize config:type="integer"
>4</stripesize>

lvm_group

If this is a physical partition used by (part of) a volume group (LVM), you need to specify the name of the volume group here.

<lvm_group>system</lvm_group>

pool

pool must be set to true if the LVM logical volume should be an LVM thin pool.

<pool config:type="boolean">false</pool>

used_pool

The name of the LVM thin pool that is used as a data store for this thin logical volume. If this is set to something non-empty, it implies that the volume is a so-called thin logical volume.

<used_pool>my_thin_pool</used_pool>

raid_name

If this physical volume is part of a RAID, specify the name of the RAID.

<raid_name>/dev/md0</raid_name>

raid_type

Specify the type of the RAID.

<raid_type>raid1</raid_type>

raid_options

Specify RAID options, see below.

<raid_options>...</raid_options>

resize

This boolean must be true if an existing partition should be resized. In this case, you want to set create to false and usually you do not want to format the partition. You need to tell AutoYaST the partition_nr and the size. The size can be in percentage of the original size or a number, like 800M. max and auto do not work as size here.

<resize config:type="boolean"
>false</resize>

Resizing only works with physical disks, not with LVM volumes.

4.5.3 Btrfs subvolumes

As mentioned in Section 4.5.2, “Partition Configuration”, it is possible to define a set of subvolumes for each Btrfs file system. In its simplest form, is just a list of entries:

<subvolumes config:type="list">
  <path>tmp</path>
  <path>opt</path>
  <path>srv</path>
  <path>var/crash</path>
  <path>var/lock</path>
  <path>var/run</path>
  <path>var/tmp</path>
  <path>var/spool</path>
</subvolumes>

AutoYaST supports disabling copy-on-write for a given subvolume. In that case, a slightly more complex syntax should be used:

<subvolumes config:type="list">
<listentry>tmp</listentry>
<listentry>opt</listentry>
<listentry>srv</listentry>
<listentry>
  <path>var/lib/pgsql</path>
  <copy_on_write config:type="boolean">false</copy_on_write>
</listentry>
</subvolumes>

If there is a default subvolume used for the distribution (for example @ in SUSE Linux Enterprise Server), the name of this default subvolume is automatically prefixed to the names in this list. This behavior can be disabled by setting the btrfs_set_default_subvolume_name in the general/storage section.

<general>
  <storage>
    <btrfs_set_default_subvolume_name config:type="boolean">false</btrfs_set_default_subvolume_name>
  </storage>
</general>

4.5.4 Using the Whole Disk

AutoYaST will format a whole disk as a single partition by setting the partition_nr to 0 as described in Section 4.5.1, “Drive Configuration”. In such cases, the configuration in the first partition from the drive will be applied to the whole disk.

In the example below, we are using the second disk (/dev/sdb) as the /home file system.

Example 4.3: Using a Whole Disk as a File System
<partitioning config:type="list">
  <drive>
    <device>/dev/sda</device>
    <partitions config:type="list">
      <partition>
        <create config:type="boolean">true</create>
        <format config:type="boolean">true</format>
        <mount>/</mount>
        <size>max</size>
      </partition>
    </partitions>
  </drive>
  <drive>
    <device>/dev/sdb</device>
    <partitions config:type="list">
      <partition>
        <partition_nr config:type="integer">0<partition_nr>
        <format config:type="boolean">true</format>
        <mount>/home</mount>
      </partition>
    </partitions>
  </drive>

In addition, the whole disk can be used as an LVM physical volume or as a software RAID member. See Section 4.5.9, “Logical Volume Manager (LVM)” and Section 4.5.10, “Software RAID” for further details about setting up an LVM or a software RAID.

4.5.5 RAID Options

The following elements must be placed within the following XML structure:

<partition>
  <raid_options>
    ...
  </raid_options>
</partition>

Attribute

Values

Description

chunk_size

<chunk_size>4</chunk_size>

parity_algorithm

Possible values are:

left_asymmetric, left_symmetric, right_asymmetric, right_symmetric.

For RAID6 and RAID10 the following values can be used:

parity_first, parity_last, left_asymmetric_6, left_symmetric_6, right_asymmetric_6, right_symmetric_6, parity_first_6, n2, o2, f2, n3, o3, f3 for RAID6 and RAID10.

<parity_algorithm
>left_asymmetric</parity_algorithm>

raid_type

Possible values are: raid0, raid1, raid5, raid6 and raid10.

<raid_type>raid1</raid_type>

The default is raid1.

device_order

This list contains the optional order of the physical devices:

<device_order config:type="list">
   <device>/dev/sdb2</device>
   <device>/dev/sda1</device>
   ...
</device_order>

This is optional and the default is alphabetical order.

4.5.6 Automated Partitioning

For automated partitioning, you only need to provide the sizes and mount points of partitions. All other data needed for successful partitioning is calculated during installation—unless provided in the control file.

If no partitions are defined and the specified drive is also the drive where the root partition should be created, the following partitions are created automatically:

  • /boot

    The size of the /boot partition is determined by the architecture of the target system.

  • swap

    The size of the swap partition is determined by the amount of memory available in the system.

  • / (root partition)

    The size of the root partition is determined by the space left after creating swap and /boot.

Depending on the initial status of the drive and how it was previously partitioned, it is possible to create the default partitioning in the following ways:

Use Free Space

If the drive is already partitioned, it is possible to create the new partitions using the free space on the hard disk. This requires the availability of sufficient space for all selected packages in addition to swap.

Reuse all available space

Use this option to delete all existing partitions (Linux and non-Linux).

Reuse all available Linux partitions

This option deletes all existing Linux partitions. Other partitions (for example Windows partitions) remain untouched. Note that this works only if the Linux partitions are at the end of the device.

Reuse only specified partitions

This option allows you to select specific partitions to delete. Start the selection with the last available partition.

Repartitioning only works if the selected partitions are neighbors and located at the end of the device.

Important
Important: Beware of Data Loss

The value provided in the use property determines how existing data and partitions are treated. The value all means that the entire disk will be erased. Make backups and use the confirm property if you need to keep some partitions with important data. Otherwise, no pop-ups will notify you about partitions being deleted.

If multiple drives are in the target system, identify all drives with their device names and specify how the partitioning should be performed.

Partition sizes can be given in gigabytes, megabytes or can be set to a flexible value using the keywords auto and max. max uses all available space on a drive, therefore should only be set for the last partition on the drive. With auto the size of a swap or boot partition is determined automatically, depending on the memory available and the type of the system.

A fixed size can be given as shown below:

1GB, 1G, 1000MB, or 1000M will all create a partition of the size 1 Gigabyte.

Example 4.4: Automated Partitioning

The following is an example of a single drive system, which is not pre-partitioned and should be automatically partitioned according to the described pre-defined partition plan. If you do not specify the device, it will be automatically detected.

<partitioning  config:type="list">
  <drive>
    <device>/dev/sda</device>
    <use>all</use>
  </drive>
</partitioning>

A more detailed example shows how existing partitions and multiple drives are handled.

Example 4.5: Detailed Automated Partitioning
<partitioning  config:type="list">
  <drive>
    <device>/dev/sda</device>
    <partitions config:type="list">
      <partition>
        <mount>/</mount>
        <size>10G</size>
      </partition>
      <partition>
        <mount>swap</mount>
        <size>1G</size>
      </partition>
    </partitions>
  </drive>
  <drive>
    <device>/dev/sdb</device>
    <use>all</use>
    <partitions config:type="list">
      <partition>
        <filesystem  config:type="symbol">reiser</filesystem>
        <mount>/data1</mount>
        <size>15G</size>
      </partition>
      <partition>
        <filesystem  config:type="symbol">jfs</filesystem>
        <mount>/data2</mount>
        <size>auto</size>
      </partition>
    </partitions>
    <use>free</use>
  </drive>
</partitioning>

4.5.7 Advanced Partitioning Features

4.5.7.1 Wipe out Partition Table

Usually this is not needed because AutoYaST can delete partitions one by one automatically. But you need the option to let AutoYaST clear the partition table instead of deleting partitions individually.

Go to the drive section and add:

<initialize config:type="boolean">true</initialize>

With this setting AutoYaST will delete the partition table before it starts to analyze the actual partitioning and calculates its partition plan. Of course this means, that you cannot keep any of your existing partitions.

4.5.7.2 Mount Options

By default a file system to be mounted is identified in /etc/fstab by the device name. This identification can be changed so the file system is found by searching for a UUID or a volume label. Note that not all file systems can be mounted by UUID or a volume label. To specify how a partition is to be mounted, use the mountby property which has the symbol type. Possible options are:

  • device (default)

  • label

  • UUID

If you choose to mount the partition using a label, the name entered for the label property is used as the volume label.

Add any valid mount option in the fourth field of /etc/fstab. Multiple options are separated by commas. Possible fstab options:

Mount read-only (ro)

No write access to the file system. Default is false.

No access time (noatime)

Access times are not updated when a file is read. Default is false.

Mountable by User (user)

The file system can be mounted by a normal user. Default is false.

Data Journaling Mode (ordered, journal, writeback)
journal

All data is committed to the journal prior to being written to the main file system.

ordered

All data is directly written to the main file system before its metadata is committed to the journal.

writeback

Data ordering is not preserved.

Access Control List (acl)

Enable access control lists on the file system.

Extended User Attributes (user_xattr)

Allow extended user attributes on the file system.

Example 4.6: Mount Options
<partitions config:type="list">
  <partition>
    <filesystem config:type="symbol">reiser</filesystem>
    <format config:type="boolean">true</format>
    <fstopt>ro,noatime,user,data=ordered,acl,user_xattr</fstopt>
    <mount>/local</mount>
    <mountby config:type="symbol">uuid</mountby>
    <partition_id config:type="integer">131</partition_id>
    <size>10G</size>
  </partition>
</partitions>

4.5.7.3 Keeping Specific Partitions

In some cases you should leave partitions untouched and only format specific target partitions, rather than creating them from scratch. For example, if different Linux installations coexist, or you have another operating system installed, likely you do not want to wipe these out. You may also want to leave data partitions untouched.

Such scenarios require certain knowledge about the target systems and hard disks. Depending on the scenario, you might need to know the exact partition table of the target hard disk with partition ids, sizes and numbers. With this data you can tell AutoYaST to keep certain partitions, format others and create new partitions if needed.

The following example will keep partitions 1, 2 and 5 and delete partition 6 to create two new partitions. All remaining partitions will only be formatted.

Example 4.7: Keeping partitions
<partitioning config:type="list">
  <drive>
    <device>/dev/sdc</device>
      <partitions config:type="list">
        <partition>
          <create config:type="boolean">false</create>
          <format config:type="boolean">true</format>
          <mount>/</mount>
          <partition_nr config:type="integer">1</partition_nr>
        </partition>
        <partition>
          <create config:type="boolean">false</create>
          <format config:type="boolean">false</format>
          <partition_nr config:type="integer">2</partition_nr>
          <mount>/space</mount>
        </partition>
        <partition>
          <create config:type="boolean">false</create>
          <format config:type="boolean">true</format>
          <filesystem config:type="symbol">swap</filesystem>
          <partition_nr config:type="integer">5</partition_nr>
          <mount>swap</mount>
        </partition>
        <partition>
          <format config:type="boolean">true</format>
          <mount>/space2</mount>
          <size>5G</size>
        </partition>
        <partition>
          <format config:type="boolean">true</format>
          <mount>/space3</mount>
          <size>max</size>
        </partition>
      </partitions>
    <use>6</use>
  </drive>
</partitioning>

The last example requires exact knowledge of the existing partition table and the partition numbers of those partitions that should be kept. In some cases however, such data may not be available, especially in a mixed hardware environment with different hard disk types and configurations. The following scenario is for a system with a non-Linux OS with a designated area for a Linux installation.

Keeping partitions
Figure 4.1: Keeping partitions

In this scenario, shown in figure Figure 4.1, “Keeping partitions”, AutoYaST will not create new partitions. Instead it searches for certain partition types on the system and uses them according to the partitioning plan in the control file. No partition numbers are given in this case, only the mount points and the partition types (additional configuration data can be provided, for example file system options, encryption and file system type).

Example 4.8: Auto-detection of partitions to be kept.
<partitioning config:type="list">
  <drive>
    <partitions config:type="list">
      <partition>
        <create config:type="boolean">false</create>
        <format config:type="boolean">true</format>
        <mount>/</mount>
        <partition_id config:type="integer">131</partition_id>
      </partition>
      <partition>
        <create config:type="boolean">false</create>
        <format config:type="boolean">true</format>
        <filesystem config:type="symbol">swap</filesystem>
        <partition_id config:type="integer">130</partition_id>
        <mount>swap</mount>
      </partition>
    </partitions>
  </drive>
</partitioning>

4.5.8 Using an Existing Mount Table (fstab)

Note
Note: Cannot Be Combined with partitioning Section

This section will be ignored if you have defined your own partitioning section too.

This option will allow AutoYaST to use an existing /etc/fstab and use the partition data from a previous installation. All partitions are kept and no new partitions are created. The partitions will be formatted and mounted as specified in /etc/fstab on a Linux root partition.

Although the default behavior is to format all partitions, it is also possible to leave some partitions (for example data partitions) untouched and only mount them. If multiple installations are found on the system (multiple root partitions with different fstab files, the installation will abort, unless the root partition is configured in the control file. The following example illustrates how this option can be used:

Example 4.9: Reading an Existing /etc/fstab
<partitioning_advanced>
  <fstab>
    <!-- Read data from existing fstab. If multiple root partitions are
            found, use the one specified below. Otherwise the first root
            partition is taken -->
    <!-- <root_partition>/dev/sda5</root_partition> -->
    <use_existing_fstab config:type="boolean">true</use_existing_fstab>
    <!-- all partitions found in fstab will be formatted and mounted
            by default unless a partition is listed below with different
            settings -->
    <partitions config:type="list">
      <partition>
        <format config:type="boolean">false</format>
        <mount>/bootmirror</mount>
      </partition>
    </partitions>
  </fstab>
</partitioning_advanced>

4.5.9 Logical Volume Manager (LVM)

To configure LVM, first create a physical volume using the normal partitioning method described above.

Example 4.10: Create LVM Physical Volume

The following example shows how to prepare for LVM in the partitioning resource. A non-formatted partition is created on device /dev/sda1 of the type LVM and with the volume group system. This partition will use all space available on the drive.

<partitioning config:type="list">
  <drive>
    <device>/dev/sda</device>
    <partitions config:type="list">
      <partition>
        <create config:type="boolean">true</create>
        <lvm_group>system</lvm_group>
        <partition_type>primary</partition_type>
        <partition_id config:type="integer">142</partition_id>
        <partition_nr config:type="integer">1</partition_nr>
        <size>max</size>
      </partition>
    </partitions>
    <use>all</use>
  </drive>
</partitioning>
Example 4.11: LVM Logical Volumes
<partitioning config:type="list">
  <drive>
    <device>/dev/sda</device>
    <partitions config:type="list">
      <partition>
        <lvm_group>system</lvm_group>
        <partition_type>primary</partition_type>
        <size>max</size>
      </partition>
    </partitions>
    <use>all</use>
  </drive>
  <drive>
    <device>/dev/system</device>
      <is_lvm_vg config:type="boolean">true</is_lvm_vg>
      <partitions config:type="list">
        <partition>
          <filesystem config:type="symbol">reiser</filesystem>
          <lv_name>user_lv</lv_name>
          <mount>/usr</mount>
          <size>15G</size>
        </partition>
        <partition>
          <filesystem config:type="symbol">reiser</filesystem>
          <lv_name>opt_lv</lv_name>
          <mount>/opt</mount>
          <size>10G</size>
        </partition>
        <partition>
          <filesystem config:type="symbol">reiser</filesystem>
          <lv_name>var_lv</lv_name>
          <mount>/var</mount>
          <size>1G</size>
        </partition>
      </partitions>
      <pesize>4M</pesize>
    <use>all</use>
  </drive>
</partitioning>

It is possible to set the size to max for the logical volumes. Of course, you can only use max for one(!) logical volume. You cannot set two logical volumes in one volume group to max.

4.5.10 Software RAID

Using AutoYaST, you can create and assemble software RAID devices. The supported RAID levels are the following:

RAID 0

This level increases your disk performance. There is no redundancy in this mode. If one of the drives crashes, data recovery will not be possible.

RAID 1

This mode offers the best redundancy. It can be used with two or more disks. An exact copy of all data is maintained on all disks. As long as at least one disk is still working, no data is lost. The partitions used for this type of RAID should have approximately the same size.

RAID 5

This mode combines management of a larger number of disks and still maintains some redundancy. This mode can be used on three disks or more. If one disk fails, all data is still intact. If two disks fail simultaneously, all data is lost.

Multipath

This mode allows access to the same physical device via multiple controllers for redundancy against a fault in a controller card. This mode can be used with at least two devices.

As with LVM, you need to create all RAID partitions first and assign them to the RAID device you want to create afterward. Additionally you need to specify whether a partition or a device should be part of the RAID or if it should be a Spare device.

The following example shows a simple RAID1 configuration:

Example 4.12: RAID1 configuration
<partitioning config:type="list">
  <drive>
    <device>/dev/sda</device>
    <partitions config:type="list">
      <partition>
        <partition_id config:type="integer">253</partition_id>
        <format config:type="boolean">false</format>
        <raid_name>/dev/md0</raid_name>
        <raid_type>raid</raid_type>
        <size>4G</size>
      </partition>

        <!-- Insert a configuration for the regular partitions located on
                /dev/sda here (for example / and swap) -->

    </partitions>
    <use>all</use>
  </drive>
  <drive>
    <device>/dev/sdb</device>
    <partitions config:type="list">
      <partition>
        <format config:type="boolean">false</format>
        <partition_id config:type="integer">253</partition_id>
        <raid_name>/dev/md0</raid_name>
        <raid_type>raid</raid_type>
        <size>4gb</size>
      </partition>
    </partitions>
    <use>all</use>
  </drive>
  <drive>
    <device>/dev/md</device>
    <partitions config:type="list">
      <partition>
        <filesystem config:type="symbol">reiser</filesystem>
        <format config:type="boolean">true</format>
        <mount>/space</mount>
        <partition_id config:type="integer">131</partition_id>
        <partition_nr config:type="integer">0</partition_nr>
        <raid_options>
          <chunk_size>4</chunk_size>
          <parity_algorithm>left-asymmetric</parity_algorithm>
          <raid_type>raid1</raid_type>
        </raid_options>
      </partition>
    </partitions>
    <use>all</use>
  </drive>
</partitioning>

Keep the following in mind when configuring a RAID:

  • The device for raid is always /dev/md

  • The property partition_nr is used to determine the MD device number. If partition_nr is equal to 0, then /dev/md0 is configured.

  • All RAID-specific options are contained in the raid_options resource.

4.5.11 Multipath Support

AutoYaST is able to handle multipath devices. In order to take advantage of them, you need to enable multipath support, as described in Section 4.1.6, “The Storage Section”, and set the type element of each drive section to CT_DMMULTIPATH, instead of CT_DISK. Mixing CT_DISK and CT_DMMULTIPATH types will not work.

Example 4.13, “Using Multipath Devices” shows the relevant parts of a profile that instructs AutoYaST to partition a multipath device.

Example 4.13: Using Multipath Devices
<general>
  <storage>
    <start_multipath config:type="boolean">true</start_multipath>
  <storage>
</general>
<partitioning>
  <drive>
    <partitions config:type="list">
      <partition>
        <size>20G</size>
        <mount>/</mount>
        <filesystem config:type="symbol">ext4</filesystem>
      </partition>
      <partition>
        <size>auto</size>
        <mount>swap</mount>
      </partition>
    </partitions>
    <type config:type="symbol">CT_DMMULTIPATH</type>
    <use>all</use>
  </drive>
</partitioning>

4.5.12.2 Configuring zFCP disks

The following elements must be placed within the following XML structure:

<profile>
  <zfcp>
    <devices config:type="list">
      <listentry>
        ...
      </listentry>
    </devices>
  </zfcp>
<profile>

Each disk needs to be configured in a separate listentry section.

controller_id

Channel number

<controller_id>0.0.fc00</controller_id>

The controller_id element is required.

There are two optional elements, wwpn (Worldwide Port Number, the target port through which the SCSI device is attached), and fcp_lun (logical unit number of the SCSI device). It is not necessary to specify these for FCP devices running in NPIV (Node Port ID Virtualization) mode, and when the zfcp module parameter allow_lun_scan is set to 1 (the default setting), which enables automatic LUN scanning by the zfcp device driver.

If automatic LUN scanning is not available, set the wwpn and fcp_lun options manually.

wwpn

Worldwide port number

<wwpn>0x500507630300c562</wwpn>
fcp_lun

Logical unit number

<fcp_lun>0x4010403200000000</fcp_lun>

4.9 Software

4.9.1 Package Selection with Patterns

Patterns are configured like this:

Example 4.19: Package Selection in the Control File with Patterns
<software>
  <patterns config:type="list">
    <pattern>directory_server</pattern>
  </patterns>
  <packages  config:type="list">
    <package>apache</package>
    <package>postfix</package>
  </packages>
  <do_online_update config:type="boolean">true</do_online_update>
</software>

It is possible to specify package and pattern names using regular expressions. In that case, AutoYaST will select all packages or patterns that match the expression. Beware that such expressions must be enclosed within slashes. In Example 4.20, “Packages selection using a regular expression”, all packages whose name starts with nginx will be selected (e.g., nginx and nginx-macros).

Example 4.20: Packages selection using a regular expression
<software>
  <packages config:type="list">
    <package>/nginx.*/</package>
  </packages>
</software>

4.9.2 Installing Additional/Customized Packages or Products

In addition to the packages available for installation on the DVD-ROMs, you can add external packages including customized kernels. Customized kernel packages must be compatible to the SUSE packages and must install the kernel files to the same locations.

Unlike in earlier in versions, you do not need a special resource in the control file to install custom and external packages. Instead you need to re-create the package database and update it with any new packages or new package versions in the source repository.

A script is provided for this task which will query packages available in the repository and create the package database. Use the command /usr/bin/create_package_descr. It can be found in the inst-source-utils package in the openSUSE Build Service. When creating the database, all languages will be reset to English.

Example 4.21: Creating a Package Database With the Additional Package inst-source-utils.rpm

The unpacked DVD is located in /usr/local/DVDs/LATEST.

cp /tmp/inst-source-utils-2016.7.26-1.2.noarch.rpm /usr/local/DVDs/LATEST/suse/noarch
cd /usr/local/DVDs/LATEST/suse
create_package_descr -d /usr/local/CDs/LATEST/suse

In the above example, the directory /usr/local/CDs/LATEST/suse contains the architecture dependent (for example x86_64) and architecture independent packages (noarch). This might look different on other architectures.

The advantage of this method is that you can keep an up-to-date repository with fixed and updated package. Additionally this method makes the creation of custom CD-ROMs easier.

To add your own module such as the SDK (SUSE Software Development Kit), add a file add_on_products.xml to the installation source in the root directory.

The following example shows how the SDK module can be added to the base product repository. The complete SDK repository will be stored in the directory /sdk.

Example 4.22: add_on_products.xml

This file describes an SDK module included in the base product.

<?xml version="1.0"?>
<add_on_products xmlns="http://www.suse.com/1.0/yast2ns"
   xmlns:config="http://www.suse.com/1.0/configns">
   <product_items config:type="list">
      <product_item>
         <name>SUSE Linux Enterprise Software Development Kit</name>
         <url>relurl:////sdk?alias=SLE_SDK</url>
         <path>/</path>
         <-- Users are asked whether to add such a product -->
         <ask_user config:type="boolean">false</ask_user>
         <-- Defines the default state of pre-selected state in case of ask_user used. -->
         <selected config:type="boolean">true</selected>
      </product_item>
   </product_items>
</add_on_products>

With a normal installation now the SDK module will be installed automatically. It will be not done via an AutoYaST installation. An additional entry would be needed for this in the AutoYaST control file add-on section.

Besides this special case, all other modules, extensions and add-on products can be added from almost every other location during an AutoYaST installation.

Example 4.23: Adding SDK product auto AutoYaST configuration file
<add-on>
  <add_on_products config:type="list">
    <listentry>
      <media_url>cd:///sdk</media_url>
      <product>sle-sdk</product>
      <alias>SLES SDK</alias>
      <product_dir>/</product_dir>
      <priority config:type="integer">20</priority>
      <ask_on_error config:type="boolean">false</ask_on_error>
      <confirm_license config:type="boolean">false</confirm_license>
      <name>SUSE Linux Enterprise Software Development Kit</name>
    </listentry>
  </add_on_products>
</add-on>

Attribute

Values

media_url

Product URL. Can have the prefix cd:///, http://, ftp://,...

product

Internal product name if the add-on is a product. The command zypper products shows the names of installed products.

alias

Repository alias name. Defined by the user.

product_dir

Additional subpath. Optional.

priority

Sets the repository libzypp priority. Priority of 1 is the highest. The higher the number the lower the priority. Default is 99.

ask_on_error

AutoYaST can ask the user to make add-on products, modules or extensions available instead of reporting a time-out error when no repository can be found at the given location. Set ask_on_error to true (the default is false).

confirm_license

The user has to confirm the license. Default is false.

name

Repository name. The command zypper lr shows the names of added repositories.

To use unsigned installation sources with AutoYaST, turn off the checks with the following configuration in your AutoYaST control file.

Note
Note: Unsigned Installation Sources—Limitations

You can only disable signature checking during the first stage of the auto-installation process. In stage two, the installed system's configuration takes precedence over AutoYaST configuration.

The elements listed below must be placed within the following XML structure:

<general>
  <signature-handling>
    ...
  </signature-handling>
</general>

Default values for all options are false. If an option is set to false and a package or repository fails the respective test, it is silently ignored and will not be installed. Note that setting any of these options to true is a potential security risk. Never do it when using packages or repositories from third party sources.

Attribute

Values

accept_unsigned_file

If set to true, AutoYaST will accept unsigned files like the content file.

<accept_unsigned_file config:type="boolean"
>true</accept_unsigned_file>

accept_file_without_checksum

If set to true, AutoYaST will accept files without a checksum in the content file.

<accept_file_without_checksum config:type="boolean"
>true</accept_file_without_checksum>

accept_verification_failed

If set to true, AutoYaST will accept signed files even when the verification of the signature failed.

<accept_verification_failed config:type="boolean"
>true</accept_verification_failed>

accept_unknown_gpg_key

If set to true, AutoYaST will accept new gpg keys of the installation sources, for example the key used to sign the content file.

<accept_unknown_gpg_key config:type="boolean"
>true</accept_unknown_gpg_key>

accept_non_trusted_gpg_key

Set this option to true to accept known keys you have not yet trusted.

<accept_non_trusted_gpg_key config:type="boolean"
>true</accept_non_trusted_gpg_key>

import_gpg_key

If set to true, AutoYaST will accept and import new gpg keys on the installation source in its database.

<import_gpg_key config:type="boolean"
>true</import_gpg_key>

It is possible to configure the signature handling for each add-on product, module, or extension individually. The following elements must be between the signature-handling section of the individual add-on product, module, or extension. All settings are optional. If not configured, the global signature-handling from the general section is used.

Attribute

Values

accept_unsigned_file

If set to true, AutoYaST will accept unsigned files like the content file for this add-on product.

<accept_unsigned_file config:type="boolean"
>true</accept_unsigned_file>

accept_file_without_checksum

If set to true, AutoYaST will accept files without a checksum in the content file for this add-on.

<accept_file_without_checksum config:type="boolean"
>true</accept_file_without_checksum>

accept_verification_failed

If set to true, AutoYaST will accept signed files even when the verification of the signature fails.

<accept_verification_failed config:type="boolean"
>true</accept_verification_failed>

accept_unknown_gpg_key

If all is set to true, AutoYaST will accept new gpg keys on the installation source.

<accept_unknown_gpg_key>
  <all config:type="boolean">true</all>
</accept_unknown_gpg_key>

Otherwise you can define single keys too.

<accept_unknown_gpg_key>
  <all config:type="boolean">false</all>
  <keys config:type="list">
    <keyid>3B3011B76B9D6523</keyid>
  </keys>
</accept_unknown_gpg_key>

accept_non_trusted_gpg_key

This means, the key is known, but it is not trusted by you.

You can trust all keys by adding:

<accept_non_trusted_gpg_key>
  <all config:type="boolean">true</all>
</accept_non_trusted_gpg_key>

Or you can trust specific keys:

<accept_non_trusted_gpg_key>
  <all config:type="boolean">false</all>
  <keys config:type="list">
    <keyid>3B3011B76B9D6523</keyid>
  </keys>
</accept_non_trusted_gpg_key>

import_gpg_key

If all is set to true, AutoYaST will accept and import all new gpg keys on the installation source into its database.

<import_gpg_key>
  <all config:type="boolean">true</all>
</import_gpg_key>

This can be done for specific keys only:

<import_gpg_key>
  <all config:type="boolean">false</all>
  <keys config:type="list">
    <keyid>3B3011B76B9D6523</keyid>
  </keys>
</import_gpg_key>

4.9.3 Kernel Packages

Kernel packages are not part of any selection. The required kernel is determined during installation. If the kernel package is added to any selection or to the individual package selection, installation will mostly fail because of conflicts.

To force the installation of a specific kernel, use the kernel property. The following is an example of forcing the installation of the default kernel. This kernel will be installed even if an SMP or other kernel is required.

Example 4.24: Kernel Selection in the Control File
<software>
  <kernel>kernel-default</kernel>
  ...
</software>

4.9.4 Removing Automatically Selected Packages

Some packages are selected automatically either because of a dependency or because it is available in a selection.

Removing these packages might break the system consistency, and it is not recommended to remove basic packages unless a replacement which provides the same services is provided. The best example for this case are mail transfer agent (MTA) packages. By default, postfix will be selected and installed. To use another MTA like sendmail, then postfix can be removed from the list of selected package using a list in the software resource. However, note that sendmail is not shipped with SUSE Linux Enterprise Server. The following example shows how this can be done:

Example 4.25: Package Selection in Control File
<software>
  <packages  config:type="list">
    <package>sendmail</package>
  </packages>
  <remove-packages  config:type="list">
    <package>postfix</package>
  </remove-packages>
</software>
Note
Note: Package Removal Failure

Note that it is not possible to remove a package, that is part of a pattern (see Section 4.9.1, “Package Selection with Patterns”). When specifying such a package for removal, the installation will fail with the following error message:

The package resolver run failed. Check
      your software section in the AutoYaST profile.

4.9.5 Installing Recommended Packages/Patterns

By default all recommended packages/patterns will be installed. To have a minimal installation which includes required packages only, you can switch off this behavior with the flag install_recommended. Note that this flag only affects a fresh installation and will be ignored during an upgrade.

<software>
  <install_recommended config:type="boolean">false
  </install_recommended>
</software>

Default: If this flag has not been set in the configuration file all recommended packages and no recommended pattern will be installed.

4.9.6 Installing Packages in Stage 2

To install packages after the reboot during stage two, you can use the post-packages element for that:

<software>
  <post-packages config:type="list">
    <package>yast2-cim</package>
  </post-packages>
</software>

4.9.7 Installing Patterns in Stage 2

You can also install patterns in stage 2. Use the post-patterns element for that:

<software>
  <post-patterns config:type="list">
    <pattern>apparmor</pattern>
  </post-patterns>
</software>

4.9.8 Online Update in Stage 2

You can perform an online update at the end of the installation. Set the boolean do_online_update to true. Of course this only makes sense if you add an online update repository in the suse-register/customer-center section, for example, or in a post-script. If the online update repository was already available in stage one via the add-on section, then AutoYaST has already installed the latest packages available. If a kernel update is done via online-update, a reboot at the end of stage two is triggered.

<software>
  <do_online_update config:type="boolean">true</do_online_update>
</software>

4.10 Upgrade

AutoYaST can also be used for doing a system upgrade. Besides upgrade packages, the following sections are supported too:

  • scripts/pre-scripts Running user scripts very early, before anything else really happens.

  • add-on Defining an additional add-on product.

  • language Setting language.

  • timezone Setting timezone.

  • keyboard Setting keyboard.

  • software Installing additional software/patterns. Removing installed packages.

  • suse_register Running registration process.

To control the upgrade process the following sections can be defined:

Example 4.26: Upgrade and Backup
<upgrade>
    <stop_on_solver_conflict config:type="boolean">true</stop_on_solver_conflict>
  </upgrade>
  <backup>
    <sysconfig config:type="boolean">true</sysconfig>
    <modified config:type="boolean">true</modified>
    <remove_old config:type="boolean">true</remove_old>
  </backup>

Element

Description

Comment

stop_on_solver_conflict

Halt installation if there are package dependency issues.

modified

Create backup of modified files.

sysconfig

Create backup of /etc/sysconfig directory.

remove_old

Remove backups from previous updates.

To start the AutoYaST upgrade mode, you need:

Procedure 4.1: Starting AutoYaST in Upgrade Mode
  1. Copy the AutoYaST profile to /root/autoupg.xml on its file system.

  2. Boot the system from the installation media.

  3. Select the Installation menu item.

  4. On the command line, set autoupgrade=1.

  5. Press Enter to start the upgrade process.

4.11 Services and Targets

With the services-manager resource you can set the default systemd target and specify in detail which system services you want to start or deactivate.

The default-target property specifies the default systemd target into which the system boots. Valid options are graphical for a graphical login, or multi-user for a console login.

The <enable config:type="list"> and <disable config:type="list"> let you explicitly enable or disable services.

Example 4.27: Configuring Services and Targets
<services-manager>
  <default_target>multi-user</default_target>
  <services>
    <disable config:type="list">
      <service>cups</service>
    </disable>
    <enable config:type="list">
      <service>sshd</service>
    </enable>
  </services>
</services-manager>

4.12 Network Configuration

Network configuration is used to connect a single workstation to an Ethernet-based LAN or to configure a dial-up connection. More complex configurations (multiple network cards, routing, etc.) are also provided.

If the following setting is set to true, YaST will keep network settings created during the installation (via Linuxrc) and/or merge it with network settings from the AutoYaST control file (if defined). AutoYaST settings have higher priority than already present configuration files. YaST will write ifcfg-* files based on the entries in the control file without removing old ones. If there is an empty or no DNS and routing section, YaST will keep already existing values. Otherwise settings from the control file will be applied.

<keep_install_network
config:type="boolean">true</keep_install_network>

During the second stage, installation of additional packages will take place before the network, as described in the profile, is configured. keep_install_network is set by default to true to ensure that a network is available in case it is needed to install those packages. If all packages are installed during the first stage and the network is not needed early during the second one, setting keep_install_network to false will avoid copying the configuration.

To configure network settings and activate networking automatically, one global resource is used to store the whole network configuration.

Example 4.28: Network Configuration
<networking>
  <dns>
    <dhcp_hostname config:type="boolean">true</dhcp_hostname>
    <domain>site</domain>
    <hostname>linux-bqua</hostname>

In addition to the options mentioned above, AutoYaST also supports IBM IBM Z-specific options in other sections of the configuration file. In particular, you can define the logical link address, or LLADDR (in the case of Ethernet, that is the MAC address). To do so, use the option LLADDR in the device definition.

Tip
Tip: LLADDR for VLANs

VLAN devices inherit their LLADDR from the underlying physical devices. To set a particular address for a VLAN device, set the LLADDR option for the underlying physical device.

4.12.3 Proxy

Configure your Internet proxy (caching) settings.

Configure proxies for HTTP, HTTPS, and FTP with http_proxy, https_proxy and ftp_proxy, respectively. Addresses or names that should be directly accessible need to be specified with no_proxy (space separated values). If you are using a proxy server with authorization, fill in proxy_user and proxy_password,

Example 4.30: Network configuration: Proxy
<proxy>
  <enabled config:type="boolean">true</enabled>
  <ftp_proxy>http://192.168.1.240:3128</ftp_proxy>
  <http_proxy>http://192.168.1.240:3128</http_proxy>
  <no_proxy>www.example.com .example.org localhost</no_proxy>
  <proxy_password>testpw</proxy_password>
  <proxy_user>testuser</proxy_user>
</proxy>

4.12.4 (X)Inetd

The control file has elements to specify which superserver should be used (netd_service), whether it should be enabled (netd_status) and how the services should be configured (netd_conf).

A service description element needs two parts: key and non-key. When writing the configuration, services are matched using the key fields; to the matching service, non-key fields are applied. If no service matches, it is created. If more services match, a warning is reported. The key fields are script, service, protocol and server.

service and protocol are matched literally. script is the base name of the configuration file: usually a file in /etc/xinetd.d, for example "echo-udp", or "inetd.conf". For compatibility with 8.2, server is matched more loosely: if it is /usr/sbin/tcpd, the real server name is taken from server_args. After that, the basename of the first whitespace-separated word is taken and these values are compared.

Example 4.31: Inetd Example
<profile>
  <inetd>
    <netd_service config:type="symbol">xinetd</netd_service>
    <netd_status config:type="integer">0</netd_status>
    <netd_conf config:type="list">
      <conf>
        <script>imap</script>
        <service>pop3</service>
        <enabled config:type="boolean">true</enabled>
      </conf>
      <conf>
        <server>in.ftpd</server>
        <server_args>-A</server_args>
        <enabled config:type="boolean">true</enabled>
      </conf>
      <conf>
        <service>daytime</service>
        <protocol>tcp</protocol>
      </conf>
      <conf>...</conf>
    </netd_conf>
  </inetd>
</profile>

4.13 NIS Client

Using the nis resource, you can configure the target machine as a NIS client. The following example shows a detailed configuration using multiple domains.

Example 4.32: Network configuration: NIS
 <nis>
  <nis_broadcast config:type="boolean">true</nis_broadcast>
  <nis_broken_server config:type="boolean">true</nis_broken_server>
    <nis_domain>test.com</nis_domain>
  <nis_local_only config:type="boolean">true</nis_local_only>
  <nis_options></nis_options>
  <nis_other_domains config:type="list">
    <nis_other_domain>
      <nis_broadcast config:type="boolean">false</nis_broadcast>
      <nis_domain>domain.com</nis_domain>
      <nis_servers config:type="list">
        <nis_server>10.10.0.1</nis_server>
      </nis_servers>
    </nis_other_domain>
  </nis_other_domains>
  <nis_servers config:type="list">
    <nis_server>192.168.1.1</nis_server>
  </nis_servers>
  <start_autofs config:type="boolean">true</start_autofs>
  <start_nis config:type="boolean">true</start_nis>
</nis>

4.14 NIS Server

You can configure the target machine as a NIS server. NIS Master Server and NIS Slave Server and a combination of both are available.

Example 4.33: NIS Server Configuration
  <nis_server>
    <domain>mydomain.de</domain>
    <maps_to_serve config:type="list">
      <nis_map>auto.master</nis_map>
      <nis_map>ethers</nis_map>
    </maps_to_serve>
    <merge_passwd config:type="boolean">false</merge_passwd>
    <mingid config:type="integer">0</mingid>
    <minuid config:type="integer">0</minuid>
    <nopush config:type="boolean">false</nopush>
    <pwd_chfn config:type="boolean">false</pwd_chfn>
    <pwd_chsh config:type="boolean">false</pwd_chsh>
    <pwd_srcdir>/etc</pwd_srcdir>
    <securenets config:type="list">
      <securenet>
        <netmask>255.0.0.0</netmask>
        <network>127.0.0.0</network>
      </securenet>
    </securenets>
    <server_type>master</server_type>
    <slaves config:type="list"/>
    <start_ypbind config:type="boolean">false</start_ypbind>
    <start_yppasswdd config:type="boolean">false</start_yppasswdd>

4.18 Authentication Client

The configuration file must be in the JSON format. Use the Autoinstallation Configuration module in YaST to generate a valid JSON configuration file. Install the autoyast2 package. Launch YaST and switch to the Miscellaneous › Autoinstallation Configuration. Choose Network Services › User Logon Management, press Edit, and configure the available settings. Press OK when done. To save the generated configuration file, use the File › Save.

Tip
Tip: Using ldaps://

To use LDAP with native SSL (rather than TLS), add the ldaps resource.

4.19 NFS Client and Server

Configuring a system as an NFS client or an NFS server is can be done using the configuration system. The following examples show how both NFS client and server can be configured.

From SUSE Linux Enterprise Server 12 SP5 on, the structure of NFS client configuration has changed. Some global configuration options were introduced: enable_nfs4 to switch NFS4 support on/off and idmapd_domain to define domain name for rpc.idmapd (this only makes sense when NFS4 is enabled). Attention: the old structure is not compatible with the new one and the control files with an NFS section created on older releases will not work with newer products.

Example 4.37: Network Configuration: NFS Client
<nfs>
  <enable_nfs4 config:type="boolean">true</enable_nfs4>
  <idmapd_domain>suse.cz</idmapd_domain>
  <nfs_entries config:type="list">
    <nfs_entry>
      <mount_point>/home</mount_point>
      <nfs_options>sec=krb5i,intr,rw</nfs_options>
      <server_path>saurus.suse.cz:/home</server_path>
      <vfstype>nfs4</vfstype>
    </nfs_entry>
    <nfs_entry>
      <mount_point>/work</mount_point>
      <nfs_options>defaults</nfs_options>
      <server_path>bivoj.suse.cz:/work</server_path>
      <vfstype>nfs</vfstype>
    </nfs_entry>
    <nfs_entry>
      <mount_point>/mnt</mount_point>
      <nfs_options>defaults</nfs_options>
      <server_path>fallback.suse.cz:/srv/dist</server_path>
      <vfstype>nfs</vfstype>
    </nfs_entry>
  </nfs_entries>
</nfs>
Example 4.38: Network Configuration: NFS Server
<nfs_server>
  <nfs_exports config:type="list">
    <nfs_export>
      <allowed config:type="list">
        <allowed_clients>*(ro,root_squash,sync)</allowed_clients>
      </allowed>
      <mountpoint>/home</mountpoint>
    </nfs_export>
    <nfs_export>
      <allowed config:type="list">
        <allowed_clients>*(ro,root_squash,sync)</allowed_clients>
      </allowed>
      <mountpoint>/work</mountpoint>
    </nfs_export>
  </nfs_exports>
  <start_nfsserver config:type="boolean">true</start_nfsserver>
</nfs_server>

4.20 NTP Client

Select whether to start the NTP daemon when booting the system. The NTP daemon resolves host names when initializing.

To run NTP daemon in chroot jail, set start_in_chroot. Starting any daemon in a chroot jail is more secure and strongly recommended. To adjust NTP servers, peers, local clocks, and NTP broadcasting, add the appropriate entry to the control file. An example of various configuration options is shown below.

Example 4.39: Network configuration: NTP Client
<ntp-client>
  <configure_dhcp config:type="boolean">false</configure_dhcp>
  <peers config:type="list">
    <peer>
      <address>ntp.example.com</address>
      <options></options>
      <type>server</type>
    </peer>
  </peers>
  <start_at_boot config:type="boolean">true</start_at_boot>
  <start_in_chroot config:type="boolean">true</start_in_chroot>
</ntp-client>

The following example illustrates an IPv6 configuration. You may use the server's IP address, host name, or both:

<peer>
  <address>2001:418:3ff::1:53</address>
  <comment/>
  <options/>
  <type>server</type>
</peer>

<peer>
  <address>2.pool.ntp.org</address>
  <comment/>
  <options/>
  <type>server</type>
</peer>

4.21 Mail Configuration

For the mail configuration of the client, this module lets you create a detailed mail configuration. The module contains various options. We recommended you use it at least for the initial configuration.

Example 4.40: Mail Configuration
<mail>
  <aliases config:type="list">
    <alias>
      <alias>root</alias>
      <comment></comment>
      <destinations>foo</destinations>
    </alias>
    <alias>
      <alias>test</alias>
      <comment></comment>
      <destinations>foo</destinations>
    </alias>
  </aliases>
  <connection_type config:type="symbol">permanent</connection_type>
  <fetchmail config:type="list">
    <fetchmail_entry>
      <local_user>foo</local_user>
      <password>bar</password>
      <protocol>POP3</protocol>
      <remote_user>foo</remote_user>
      <server>pop.foo.com</server>
    </fetchmail_entry>

      <server>blah.com</server>
    </fetchmail_entry>
  </fetchmail>
  <from_header>test.com</from_header>
  <listen_remote config:type="boolean">true</listen_remote>
  <local_domains config:type="list">
    <domains>test1.com</domains>
  </local_domains>
  <masquerade_other_domains config:type="list">
      <domain>blah.com</domain>
  </masquerade_other_domains>
  <masquerade_users config:type="list">
    <masquerade_user>
      <address>joe@test.com</address>
      <comment></comment>

  <use_amavis config:type="boolean">true</use_amavis>
  <virtual_users config:type="list">
    <virtual_user>
      <alias>test.com</alias>
      <comment></comment>
      <destinations>foo.com</destinations>

      <comment></comment>
      <destinations>bar.com</destinations>
    </virtual_user>
  </virtual_users>
</mail>

4.22 HTTP Server Configuration

This section is used for configuration of an Apache HTTP server.

For less experienced users, we would suggest to configure the Apache server using the HTTP server YaST module. After that, call the AutoYaST configuration module, select the HTTP server YaST module and clone the Apache settings. These settings can be exported via the menu File.

Example 4.41: HTTP Server Configuration
  <http-server>
    <Listen config:type="list">
      <listentry>
        <ADDRESS/>
        <PORT>80</PORT>
      </listentry>
    </Listen>
    <hosts config:type="list">
      <hosts_entry>
        <KEY>main</KEY>
        <VALUE config:type="list">

The usual value is /tftpboot. The directory will be created if it does not exist. The server uses this as its root directory (using the -s option).

4.26 Firstboot Workflow

The YaST firstboot utility (YaST Initial System Configuration), which runs after the installation is completed, lets you configure the before creation of the install image. On the first boot after configuration, users are then guided through a series of steps that allow for easier configuration of their desktops. YaST firstboot does not run by default and needs to be configured to run.

Example 4.45: Enabling Firstboot Workflow
      <firstboot>
        <firstboot_enabled config:type="boolean">true</firstboot_enabled>
      </firstboot>

4.27 Security Settings

Using the features of this module, you can to change the local security settings on the target system. The local security settings include the boot configuration, login settings, password settings, user addition settings, and file permissions.

Configuring the security settings automatically is similar to the Custom Settings in the security module available in the running system. This allows you create a customized configuration.

Example 4.46: Security configuration

See the reference for the meaning and the possible values of the settings in the following example.

<security>
  <console_shutdown>ignore</console_shutdown>
  <displaymanager_remote_access>no</displaymanager_remote_access>
  <fail_delay>3</fail_delay>
  <faillog_enab>yes</faillog_enab>

  <run_updatedb_as>nobody</run_updatedb_as>
  <uid_max>60000</uid_max>
  <uid_min>500</uid_min>
</security>

4.27.1 Password Settings Options

Change various password settings. These settings are mainly stored in the /etc/login.defs file.

Use this resource to activate one of the encryption methods currently supported. If not set, DES is configured.

DES, the Linux default method, works in all network environments, but it restricts you to passwords no longer than eight characters. MD5 allows longer passwords, thus provides more security, but some network protocols do not support this, and you may have problems with NIS. Blowfish is also supported.

Additionally, you can set up the system to check for password plausibility and length etc.

4.27.2 Boot Settings

Use the security resource, to change various boot settings.

How to interpret CtrlAltDel?

When someone at the console has pressed the CtrlAltDel key combination, the system usually reboots. Sometimes it is desirable to ignore this event, for example, when the system serves as both workstation and server.

Shutdown behavior of GDM

Configure a list of users allowed to shut down the machine from GDM.

4.27.3 Login Settings

Change various login settings. These settings are mainly stored in the /etc/login.defs file.

4.27.4 New user settings (useradd settings)

Set the minimum and maximum possible user and group ID

4.28 Linux Audit Framework (LAF)

This module allows the configuration of the audit daemon and to add rules for the audit subsystem.

Example 4.47: LAF configuration
  <audit-laf>
    <auditd>
      <flush>INCREMENTAL</flush>
      <freq>20</freq>
      <log_file>/var/log/audit/audit.log</log_file>
      <log_format>RAW</log_format>
      <max_log_file>5</max_log_file>
      <max_log_file_action>ROTATE</max_log_file_action>
      <name_format>NONE</name_format>
      <num_logs>4</num_logs>
    </auditd>
    <rules/>
  </audit-laf>

Attribute

Values

Description

auditd/flush

Describes how to write the data to disk.

If set to INCREMENTAL the Frequency parameter tells how many records to write before issuing an explicit flush to disk. NONE means: no special effort is made to flush data, DATA: keep data portion synchronized, SYNC: keep data and metadata fully synchronized.

auditd/freq

This parameter tells how many records to write before issuing an explicit flush to disk.

The parameter flush needs to be set to INCREMENTAL.

auditd/log_file

The full path name to the log file.

auditd/log_fomat

How much information needs to be logged.

Set RAW to log all data (store in a format exactly as the kernel sends it) or NOLOG to discard all audit information instead of writing it to disk (does not affect data sent to the dispatcher).

auditd/max_log_file

How much information needs to be logged.

Unit: Megabytes

auditd/num_logs

Number of log files.

max_log_file_action needs to be set to ROTATE

auditd/max_log_file_action

What happens if the log capacity has been reached.

If the action is set to ROTATE the Number of Log Files specifies the number of files to keep. Set to SYSLOG, the audit daemon will write a warning to /var/log/messages. With SUSPEND the daemon stops writing records to disk. IGNORE means do nothing, KEEP_LOGS is similar to ROTATE, but log files are not overwritten.

auditd/name_format

Computer Name Format describes how to write the computer name to the log file.

If USER is set, the User Defined Name is used. NONE means no computer name is inserted. HOSTNAME uses the name returned by the 'gethostname' syscall. FQD uses the fully qualified domain name.

rules

Rules for auditctl

You can edit the rules manually, which we only recommend for advanced users. For more information about all options, see man auditctl.

4.29 Users and Groups

AutoYaST supports defining local users, groups, special login settings and even default options for new users. Those settings are defined in the following sections:

users

List of users

user_defaults

Default options for new users

groups

List of groups

login_settings

Special login settings like password-less login or autologin

Note
Note: Users and groups set up during the first stage

Users and groups are set up during the first stage, so you can set up a usable system without running the second stage.

4.29.1 Users

A list of users can be defined in the <users> section. Take into account that at least the root users should be set up so you can log in after the installation is finished.

Example 4.48: Minimal User Configuration
<users config:type="list">
  <user>
    <username>root</username>
    <user_password>password</user_password>
    <encrypted config:type="boolean">false</encrypted>
  </user>
    <user>
    <username>tux</username>
    <user_password>password</user_password>
    <encrypted config:type="boolean">false</encrypted>
  </user>
</users>

The following example shows a more complex scenario. System-wide default settings from /etc/default/useradd, such as the shell or the parent directory for the home directory, are applied.

Example 4.49: Complex User Configuration
<users config:type="list">
  <user>
    <username>root</username>
    <user_password>password</user_password>
    <uid>1001</uid>
    <gid>100</gid>
    <encrypted config:type="boolean">false</encrypted>
    <fullname>Root User</fullname>
    <authorized_keys config:type="list">
      <listentry>command="/opt/login.sh" ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQDKLt1vnW2vTJpBp3VK91rFsBvpY97NljsVLdgUrlPbZ/L51FerQQ+djQ/ivDASQjO+567nMGqfYGFA/De1EGMMEoeShza67qjNi14L1HBGgVojaNajMR/NI2d1kDyvsgRy7D7FT5UGGUNT0dlcSD3b85zwgHeYLidgcGIoKeRi7HpVDOOTyhwUv4sq3ubrPCWARgPeOLdVFa9clC8PTZdxSeKp4jpNjIHEyREPin2Un1luCIPWrOYyym7aRJEPopCEqBA9HvfwpbuwBI5F0uIWZgSQLfpwW86599fBo/PvMDa96DpxH1VlzJlAIHQsMkMHbsCazPNC0++Kp5ZVERiH root@example.net</listentry>
    </authorized_keys>
  </user>
  <user>
    <username>tux</username>
    <user_password>password</user_password>
    <uid>1002</uid>
    <gid>100</gid>
    <encrypted config:type="boolean">false</encrypted>
    <fullname>Plain User</fullname>
    <home>/Users/plain</home>
    <password_settings>
      <max>120</max>
      <inact>5</inact>
    </password_settings>
  </user>
</users>
Note
Note: authorized_keys File Will Be Overwritten

If the profile defines a set of SSH authorized keys for a user in the authorized_keys section, an existing $HOME/.ssh/authorized_keys file will be overwritten. If not existing, the file will be created with the content specified. Avoid overwriting an existing authorized_keys by not specifying the respective section in the AutoYaST control file.

Note
Note: Specifying a user ID (uid)

Each user on a Linux system has a numeric user ID. You can either specify such a user ID within the AutoYaST control file manually by using uid, or let the system automatically choose a user ID by not using uid.

User IDs should be unique throughout the system. If not, some applications such as the login manager gdm may no longer work as expected.

When adding users with the AutoYaST control file, it is strongly recommended not to mix user defined IDs and automatically provided IDs. When doing so, unique IDs cannot be guaranteed. Either specify IDs for all users added with the AutoYaST control file or let the system choose the ID for all users.

Warning
Warning: Do Not Create a Superuser Account with a Name Other Than root

While it is technically possible to create an account with the user ID (uid) 0 and a name other than root, certain applications, scripts or third-party products may rely on the existence of a user called root. While such a configuration always targets individual environments, necessary adjustments could be overwritten by vendor updates, so this becomes an ongoing task, not a one-time setting. This is especially true in very complex setups involving third-party applications, where it needs to be verified with every involved vendor whether a rename of the root account is supported.

As the implications for renaming the root account cannot be foreseen, SUSE does not support renaming the root account.

Usually, the idea behind renaming the root account is to hide it or make it unpredictable. However, /etc/passwd requires 644 permissions for regular users, so any user of the system can retrieve the login name for the user ID 0. For better ways to secure the root account, refer to Section 2.30, “Restricting root Logins” and Section 2.30.3, “Restricting SSH Logins”.

4.30 Custom User Scripts

By adding scripts to the auto-installation process you can customize the installation according to your needs and take control in different stages of the installation.

In the auto-installation process, five types of scripts can be executed at different points in time during the installation:

All scripts need to be in the <scripts> section.

  • pre-scripts (very early, before anything else really happens)

  • postpartitioning-scripts (after partitioning and mounting to /mnt but before RPM installation)

  • chroot-scripts (after the package installation, before the first boot)

  • post-scripts (during the first boot of the installed system, no services running)

  • init-scripts (during the first boot of the installed system, all services up and running)

4.30.1 Pre-Install Scripts

Executed before YaST does any real change to the system (before partitioning and package installation but after the hardware detection).

You can use a pre-script to modify your control file and let AutoYaST reread it. Find your control file in /tmp/profile/autoinst.xml. Adjust the file and store the modified version in /tmp/profile/modified.xml. AutoYaST will read the modified file after the pre-script finishes.

It is also possible to change the partitioning in your pre-script.

Note
Note: Pre-Install Scripts with Confirmation

Pre-scripts are executed at an early stage of the installation. This means if you have requested to confirm the installation, the pre-scripts will be executed before the confirmation screen shows up (profile/install/general/mode/confirm).

Note
Note: Pre-Install and Zypper

To call zypper in the pre-install script you will need to set the environment variable ZYPP_LOCKFILE_ROOT="/var/run/autoyast" to prevent conflicts with the running YaST process.

Pre-Install Script elements must be placed as follows:

<scripts>
  <pre-scripts config:type="list">
    <script>
      ...
    </script>
  </pre-scripts>
</scripts>

4.30.2 Post-partitioning Scripts

Executed after YaST has done the partitioning and written the fstab. The empty system is already mounted to /mnt.

Post-partitioning script elements must be placed as follows:

<scripts>
  <postpartitioning-scripts config:type="list">
    <script>
      ...
    </script>
  </postpartitioning-scripts>
</scripts>

4.30.3 Chroot Environment Scripts

Chroot scripts are executed before the machine reboots for the first time. You can execute chroot scripts before the installation chroots into the installed system and configures the boot loader or you can execute a script after the chroot into the installed system has happened (look at the chrooted parameter for that).

Chroot Environment script elements must be placed as follows:

<scripts>
  <chroot-scripts config:type="list">
    <script>
      ...
    </script>
  </chroot-scripts>
</scripts>

4.30.4 Post-Install Scripts

These scripts are executed after AutoYaST has completed the system configuration and after it has booted the system for the first time.

Post-install script elements must be placed as follows:

<scripts>
    <post-scripts config:type="list">
      <script>
        ...
      </script>
    </post-scripts>
  </scripts>

4.30.5 Init Scripts

These scripts are executed when YaST has finished, during the initial boot process after the network has been initialized. These final scripts are executed using /usr/lib/YaST2/bin/autoyast-initscripts.sh and are executed only once. Init scripts are configured using the tag init-scripts.

The following elements must be between the <scripts><init-scripts config:type="list"><script> ... </script></init-scripts>...</scripts> tags

Table 4.1: Init script XML representation

Description

Comment

location

Define a location from where the script gets fetched. Locations can be the same as for the profile (HTTP, FTP, NFS, etc.).

<location
>http://10.10.0.1/myInitScript.sh</location>

Either <location> or <source> must be defined.

source

The script itself (source code), encapsulated in a CDATA tag. If you do not want to put the whole shell script into the XML profile, use the location parameter.

echo "Testing the init script" >
/tmp/init_out.txt
]]>
</source>

Either <location> or <source> must be defined.

filename

The file name of the script. It will be stored in a temporary directory under /tmp

<filename>mynitScript5.sh</filename>

Optional in case you only have a single init script. The default name (init-scripts) is used in this case. If having specified more than one init script, you must set a unique name for each script.

rerun

A script is only run once. Even if you use ayast_setup to run an XML file multiple times, the script is only run once. Change this default behavior by setting this boolean to true.

<rerun config:type="boolean">true</rerun>

Optional. Default is false (scripts only run once).

When added to the control file manually, scripts need to be included in a CDATA element to avoid confusion with the file syntax and other tags defined in the control file.

4.30.6 Script XML Representation

Most of the XML elements described below can be used for all the script types described above, except for init scripts, whose definitions can contain only a subset of these elements. See Section 4.30.5, “Init Scripts” for further information about them.

Table 4.2: Script XML Representation

Element

Description

Comment

location

Define a location from where the script gets fetched. Locations can be the same as for the control file (HTTP, FTP, NFS, etc.).

<location
>http://10.10.0.1/myPreScript.sh</location>

Either location or source must be defined.

source

The script itself (source code), encapsulated in a CDATA tag. If you do not want to put the whole shell script into the XML control file, refer to the location parameter.

<source>
<![CDATA[
echo "Testing the pre script" > /tmp/pre-script_out.txt
]]>
</source>

Either location or source must be defined.

interpreter

Specify the interpreter that must be used for the script. Supported options are shell and perl.

<interpreter>perl</interpreter>

Optional (default is shell).

file name

The file name of the script. It will be stored in a temporary directory under /tmp.

<filename>myPreScript5.sh</filename>

Optional. Default is the type of the script (pre-scripts in this case). If you have more than one script, you should define different names for each script.

feedback

If this boolean is true, output and error messages of the script (STDOUT and STDERR) will be shown in a pop-up. The user needs to confirm them via the OK button.

<feedback config:type="boolean">true</feedback>

Optional, default is false.

feedback_type

This can be message, warning or error. Set the timeout for these pop-ups in the <report> section.

<feedback_type>warning</feedback_type>

Optional, if missing, an always blocking pop-up is used.

debug

If this is true, every single line of a shell script is logged. Perl scripts are run with warnings turned on.

<debug config:type="boolean">true</debug>

Optional, default is true.

notification

This text will be shown in a pop-up for the time the script is running in the background.

<notification>Please wait while script is running...</notification>

Optional, if not configured, no notification pop-up will be shown.

param-list

It is possible to specify parameters given to the script being called. You may have more than one param entry. They are concatenated by a single space character on the script command line. If any shell quoting should be necessary (for example to protect embedded spaces) you need to include this.

<param-list config:type="list">
  <param>par1</param>
  <param>par2 par3</param>
  <param>"par4.1 par4.2"</param>
</param-list>

Optional, if not configured, no parameters get passed to script.

rerun

A script is only run once. Even if you use ayast_setup to run an XML file multiple times, the script is only run once. Change this default behavior by setting this boolean to true.

<rerun config:type="boolean">true</rerun>

Optional, default is false (scripts only run once).

chrooted

If set to false, the installed system remains mounted at /mnt and no chroot happens. The boot loader is not installed either at this stage. Setting it to true means, a chroot into /mnt is performed, where the installed system is mounted. The boot loader is installed, and if you want to change anything in the installed system, you do not need to use the /mnt prefix anymore.

<chrooted config:type="boolean"
>true</chrooted>

Optional, default is false. This option is only available for chroot environment scripts.

</profile>

After installation is finished, the scripts and the output logs can be found in the directory /var/adm/autoinstall. The scripts are located in the subdirectory scripts and the output logs in the log directory.

The log consists of the output produced when executing the shell scripts using the following command:

/bin/sh -x SCRIPT_NAME 2&>/var/adm/autoinstall/logs/SCRIPT_NAME.log

4.31 System Variables (Sysconfig)

Using the sysconfig resource, it is possible to define configuration variables in the sysconfig repository (/etc/sysconfig) directly. Sysconfig variables, offer the possibility to fine-tune many system components and environment variables exactly to your needs.

The following example shows how a variable can be set using the sysconfig resource.

Example 4.53: Sysconfig Configuration
<sysconfig config:type="list" >
  <sysconfig_entry>
    <sysconfig_key>XNTPD_INITIAL_NTPDATE</sysconfig_key>
    <sysconfig_path>/etc/sysconfig/xntp</sysconfig_path>
    <sysconfig_value>ntp.host.com</sysconfig_value>
  </sysconfig_entry>
  <sysconfig_entry>
    <sysconfig_key>HTTP_PROXY</sysconfig_key>
    <sysconfig_path>/etc/sysconfig/proxy</sysconfig_path>
    <sysconfig_value>proxy.host.com:3128</sysconfig_value>
  </sysconfig_entry>
  <sysconfig_entry>
    <sysconfig_key>FTP_PROXY</sysconfig_key>
    <sysconfig_path>/etc/sysconfig/proxy</sysconfig_path>
    <sysconfig_value>proxy.host.com:3128</sysconfig_value>
  </sysconfig_entry>
</sysconfig>

Both relative and absolute paths can be provided. If no absolute path is given, it is treated as a sysconfig file under the /etc/sysconfig directory.

4.32 Adding Complete Configurations

For many applications and services you may have a configuration file which should be copied to the appropriate location on the installed system. For example, if you are installing a Web server, you may have a server configuration file (httpd.conf).

Using this resource, you can embed the file into the control file by specifying the final path on the installed system. YaST will copy this file to the specified location.

This feature requires the autoyast2 package to be installed. If the package is missing, AutoYaST will automatically install the package if it is missing.

You can specify the file_location where the file should be retrieved from. This can also be a location on the network such as an HTTP server: <file_location>http://my.server.site/issue</file_location>.

You can create directories by specifying a file_path that ends with a slash.

Example 4.54: Dumping files into the installed system
<files config:type="list">
  <file>
    <file_path>/etc/apache2/httpd.conf</file_path>
    <file_contents>

<![CDATA[
some content
]]>

    </file_contents>
  </file>
  <file>
    <file_path>/mydir/a/b/c/</file_path> <!-- create directory -->
  </file>
</files>

A more advanced example is shown below. This configuration will create a file using the content supplied in file_contents and change the permissions and ownership of the file. After the file has been copied to the system, a script is executed. This can be used to modify the file and prepare it for the client's environment.

Example 4.55: Dumping files into the installed system
<files config:type="list">
  <file>
    <file_path>/etc/someconf.conf</file_path>
    <file_contents>

<![CDATA[
some content
]]>

    </file_contents>
    <file_owner>tux.users</file_owner>
    <file_permissions>444</file_permissions>
    <file_script>
      <interpreter>shell</interpreter>
      <source>

<![CDATA[
#!/bin/sh

echo "Testing file scripts" >> /etc/someconf.conf
df
cd /mnt
ls
]]>

      </source>
    </file_script>
  </file>
</files>

4.33 Ask the User for Values during Installation

You have the option to let the user decide the values of specific parts of the control file during the installation. If you use this feature, a pop-up will ask the user to enter a specific part of the control file during installation. If you want a full auto installation, but the user should set the password of the local account, you can do this via the ask directive in the control file.

The elements listed below must be placed within the following XML structure:

<general>
  <ask-list config:type="list">
    <ask>
      ...
    </ask>
  </ask-list>
</general>
Table 4.3: Ask the User for Values: XML representation

Element

Description

Comment

question

The question you want to ask the user.

<question>Enter the LDAP server</question>

The default value is the path to the element (the path often looks strange, so we recommend entering a question).

default

Set a preselection for the user. A text entry will be filled out with this value. A check box will be true or false and a selection will have the given value preselected.

<default>dc=suse,dc=de</default>

Optional.

help

An optional help text that is shown on the left side of the question.

<help>Enter the LDAP server address.</help>

Optional.

title

An optional title that is shown above the questions.

<title>LDAP server</title>

Optional.

type

The type of the element you want to change. Possible values are symbol, boolean, string and integer. The file system in the partition section is a symbol, while the encrypted element in the user configuration is a boolean. You can see the type of that element if you look in your control file at the config:type="...." attribute. You can also use static_text as type. A static_text is a text that does not require any user input and can be used to show information not included in the help text.

<type>symbol</type>

Optional. The default is string. If type is symbol, you must provide the selection element too (see below).

password

If this boolean is set to true, a password dialog pops up instead of a simple text entry. Setting this to true only makes sense if type is string.

<password config:type="boolean">true</password>

Optional. The default is false.

pathlist

A list of path elements. A path is a comma separated list of elements that describes the path to the element you want to change. For example, the LDAP server element can be found in the control file in the <ldap><ldap_server> section. So if you want to change that value, you need to set the path to ldap,ldap_server.

<pathlist config:type="list">
  <path>networking,dns,hostname</path>
  <path>...</path>
</pathlist>

To change the password of the first user in the control file, you need to set the path to users,0,user_password. The 0 indicates the first user in the <users config:type="list"> list of users in the control file. 1 would be the second one, and so on.

<users config:type="list">
  <user>
    <username>root</username>
    <user_password>password to change</user_password>
    <encrypted config:type="boolean">false</encrypted>
  </user>
  <user>
    <username>tux</username>
    <user_password>password to change</user_password>
    <encrypted config:type="boolean">false</encrypted>
  </user>
</users>

This information is optional but you should at least provide path or file.

file

You can store the answer to a question in a file, to use it in one of your scripts later. If you ask during stage=initial and you want to use the answer in stage 2, then you need to copy the answer-file in a chroot script that is running as chrooted=false. Use the command: cp /tmp/my_answer /mnt/tmp/. The reason is that /tmp in stage 1 is in the RAM disk and will be lost after the reboot, but the installed system is already mounted at /mnt/.

<file>/tmp/answer_hostname</file>

This information is optional, but you should at least provide path or file.

stage

Stage configures the installation stage in which the question pops up. You can set this value to cont or initial. initial means the pop-up comes up very early in the installation, shortly after the pre-script has run. cont means, that the dialog with the question comes after the first reboot when the system boots for the very first time. Questions you answer during the initial stage will write their answer into the control file on the hard disk. You should know that if you enter clear text passwords during initial. Of course it does not make sense to ask for the file system to use during the cont phase. The hard disk is already partitioned at that stage and the question will have no effect.

<stage>cont</stage>

Optional. The default is initial.

selection

The selection element contains a list of entry elements. Each entry represents a possible option for the user to choose. The user cannot enter a value in a text box, but he can choose from a list of values.

<selection config:type="list">
  <entry>
    <value>
        btrfs
    </value>
    <label>
        Btrfs File System
    </label>
  </entry>
  <entry>
    <value>
        ext3
    </value>
    <label>
        Extended3 File System
    </label>
  </entry>
</selection>

Optional for type=string, not possible for type=boolean and mandatory for type=symbol.

dialog

You can ask more than one question per dialog. To do so, specify the dialog-id with an integer. All questions with the same dialog-id belong to the same dialog. The dialogs are sorted by the id too.

<dialog config:type="integer">3</dialog>

Optional.

element

you can have more than one question per dialog. To make that possible you need to specify the element-id with an integer. The questions in a dialog are sorted by id.

<element config:type="integer">1</element>

Optional (see dialog).

width

You can increase the default width of dialog. If there are multiple width specifications per dialog, the largest one is used. The number is roughly equivalent to the number of characters.

<width config:type="integer">50</width>

Optional.

height

You can increase default height of dialog. If there are multiple height specifications per dialog, largest one is used. The number is roughly equivalent to number of lines.

<height config:type="integer">15</height>

Optional.

frametitle

You can have more than one question per dialog. Each question on a dialog has a frame that can have a frame title, a small caption for each question. You can put multiple elements into one frame. They need to have the same frame title.

<frametitle>User data</frametitle>

Optional. Default is no frame title.

script

You can run scripts after a question has been answered (see the table below for detailed instructions about scripts).

<script>...</script>

Optional (default is no script).

ok_label

You can change the label on the Ok button. The last element that specifies the label for a dialog wins.

<ok_label>Finish</ok_label>

Optional.

back_label

You can change the label on the Back button. The last element that specifies the label for a dialog wins.

<back_label>change values</back_label>

Optional.

timeout

You can specify an integer here that is used as timeout in seconds. If the user does not answer the question before the timeout, the default value is taken as answer. When the user touches or changes any widget in the dialog, the timeout is turned off and the dialog needs to be confirmed via Ok.

<timeout config:type="integer">30</timeout>

Optional. A missing value is interpreted as 0, which means that there is no timeout.

default_value_script

You can run scripts to set the default value for a question (see Section 4.33.1, “Default Value Scripts” for detailed instructions about default value scripts). This feature is useful if you can calculate a default value, especially in combination with the timeout option.

<default_value_script>...</default_value_script>

Optional. Default is no script.

4.33.1 Default Value Scripts

You can run scripts to set the default value for a question. This feature is useful if you can calculate a default value, especially in combination with the timeout option.

The elements listed below must be placed within the following XML structure:

<general>
  <ask-list config:type="list">
    <ask>
      <default_value_script>
        ...
      </default_value_script>
    </ask>
  </ask-list>
</general>
Table 4.4: Default Value Scripts: XML representation

Element

Description

Comment

source

The source code of the script. Whatever you echo to STDOUT will be used as default value for the ask-dialog. If your script has an exit code other than 0, the normal default element is used. Take care you use echo -n to suppress the \n and that you echo reasonable values and not okay for a boolean

<source>...</source>

This value is required, otherwise nothing would be executed.

interpreter

The interpreter to use.

<interpreter>perl</interpreter>

The default value is shell. You can also set /bin/myinterpreter as value.

4.33.2 Scripts

You can run scripts after a question has been answered.

The elements listed below must be placed within the following XML structure:

<general>
  <ask-list config:type="list">
    <ask>
      <script>
        ...

</general>
Table 4.5: Scripts: XML representation

Element

Description

Comment

file name

The file name of the script.

<filename>my_ask_script.sh</filename>

The default is ask_script.sh

source

The source code of the script. Together with rerun_on_error activated, you check the value that was entered for sanity. Your script can create a file /tmp/next_dialog with a dialog id specifying the next dialog AutoYaST will raise. A value of -1 terminates the ask sequence. If that file is not created, AutoYaST will run the dialogs in the normal order (since 11.0 only).

<source>...</source>

This value is required, otherwise nothing would be executed.

environment

A boolean that passes the value of the answer to the question as an environment variable to the script. The variable is named VAL.

<environment config:type="boolean">true</environment>

Optional. Default is false.

feedback

A boolean that turns on feedback for the script execution. STDOUT will be displayed in a pop-up window that must be confirmed after the script execution.

<feedback config:type="boolean">true</feedback>

Optional, default is false.

debug

A boolean that turns on debugging for the script execution.

<debug config:type="boolean">true</debug>

Optional, default is true. This value needs feedback to be turned on, too.

rerun_on_error

A boolean that keeps the dialog open until the script has an exit code of 0 (zero). So you can parse and check the answers the user gave in the script and display an error with the feedback option.

<rerun_on_error config:type="boolean">true</rerun_on_error>

Optional, default is false. This value should be used together with the feedback option.

Below you can see an example of the usage of the ask feature.

4.34 Kernel Dumps

Note
Note: Availability

This feature is not available on the IBM IBM Z (s390x) architecture.

With Kdump the system can create crashdump files if the whole kernel crashes. Crash dump files contain the memory contents while the system crashed. Such core files can be analyzed later by support or a (kernel) developer to find the reason for the system crash. Kdump is mostly useful for servers where you cannot easily reproduce such crashes but it is important to get the problem fixed.

There is a downside to this. Enabling Kdump requires between 64 MB and 128 MB of additional system RAM reserved for Kdump in case the system crashes and the dump needs to be generated.

This section only describes how to set up Kdump with AutoYaST. It does not describe how Kdump works. For details, refer to the kdump(7) manual page.

The following example shows a general Kdump configuration.

Example 4.56: Kdump configuration
<kdump>
  <!-- memory reservation -->
  <add_crash_kernel config:type="boolean">true</add_crash_kernel>
  <crash_kernel>256M-:64M</crash_kernel>

4.34.1 Memory Reservation

The first step is to reserve memory for Kdump at boot-up. Because the memory must be reserved very early during the boot process, the configuration is done via a kernel command line parameter called crashkernel. The reserved memory will be used to load a second kernel which will be executed without rebooting if the first kernel crashes. This second kernel has a special initrd, which contains all programs necessary to save the dump over the network or to disk, send a notification e-mail, and finally reboot.

To reserve memory for Kdump, specify the amount (such as 64M to reserve 64 MB of memory from the RAM) and the offset. The syntax is crashkernel=AMOUNT@OFFSET. The kernel can auto-detect the right offset (except for the Xen hypervisor, where you need to specify 16M as offset). The amount of memory that needs to be reserved depends on architecture and main memory. Refer to Section 17.7.1, “Manual Kdump Configuration” for recommendations on the amount of memory to reserve for Kdump.

You can also use the extended command line syntax to specify the amount of reserved memory depending on the System RAM. That is useful if you share one AutoYaST control file for multiple installations or if you often remove or install memory on one machine. The syntax is:

BEGIN_RANGE_1-END_RANGE_1:AMOUNT_1,BEGIN_RANGE_2-END_RANGE_2:AMOUNT_2@OFFSET

BEGIN_RANGE_1 is the start of the first memory range (for example: 0M) and END_RANGE_1 is the end of the first memory range (can be empty in case infinity should be assumed) and so on. For example, 256M-2G:64M,2G-:128M reserves 64 MB of crashkernel memory if the system has between 256 MB and 2 GB RAM and reserves 128 MB of crashkernel memory if the system has more than 2 GB RAM.

On the other hand, it is possible to specify multiple values for the crashkernel parameter. For example, when you need to reserve different segments of low and high memory, use values like 72M,low and 256M,high:

Example 4.57: Kdump memory reservation with multiple values
<kdump>
  <!-- memory reservation (high and low) -->
  <add_crash_kernel config:type="boolean">true</add_crash_kernel>
  <crash_kernel config:type="list">
    <listentry>72M,low</listentry>
    <listentry>256M,high</listentry>
  </crash_kernel>
</kdump>

The following table shows the settings necessary to reserve memory:

4.34.2 Dump Saving

4.34.2.1 Target

The element KDUMP_SAVEDIR specifies the URL to where the dump is saved. The following methods are possible:

  • file to save to the local disk,

  • ftp to save to an FTP server (without encryption),

  • sftp to save to an SSH2 SFTP server,

  • nfs to save to an NFS location and

  • cifs to save the dump to a CIFS/SMP export from Samba or Microsoft Windows.

For details see the kdump(5) manual page. Two examples are: file:///var/crash (which is the default location according to FHS) and ftp://user:password@host:port/incoming/dumps. A subdirectory, with the time stamp contained in the name, will be created and the dumps saved there.

When the dump is saved to the local disk, KDUMP_KEEP_OLD_DUMPS can be used to delete old dumps automatically. Set it to the number of old dumps that should be kept. If the target partition would end up with less free disk space than specified in KDUMP_FREE_DISK_SIZE, the dump is not saved.

To save the whole kernel and the debug information (if installed) to the same directory, set KDUMP_COPY_KERNEL to true. You will have everything you need to analyze the dump in one directory (except kernel modules and their debugging information).

4.34.2.2 Filtering and Compression

The kernel dump is uncompressed and unfiltered. It can get as large as your system RAM. To get smaller files, compress the dump file afterward. The dump needs to be decompressed before opening.

To use page compression, which compresses every page and allows dynamic decompression with the crash(8) debugging tool, set KDUMP_DUMPFORMAT to compressed (default).

You may not want to save all memory pages, for example those filled with zeroes. To filter the dump, set the KDUMP_DUMPLEVEL. 0 produces a full dump and 31 is the smallest dump. The manual pages kdump(5) and makedumpfile(8) list for each value which pages will be saved.

optional

4.34.3 E-Mail Notification

Configure e-mail notification if you want to be informed when a machine crashes and a dump is saved.

Because Kdump runs in the initrd, a local mail server cannot send the notification e-mail. An SMTP server needs to be specified (see below).

You need to provide exactly one address in KDUMP_NOTIFICATION_TO. More addresses can be specified in KDUMP_NOTIFICATION_CC. Only use e-mail addresses in both cases, not a real name.

Specify KDUMP_SMTP_SERVER and (if the server needs authentication) KDUMP_SMTP_USER and KDUMP_SMTP_PASSWORD. Support for TLS/SSL is not available but may be added in the future.

4.34.4 Kdump Kernel Settings

As already mentioned, a special kernel is booted to save the dump. If you do not want to use the auto-detection mechanism to find out which kernel is used (see the kdump(5) manual page that describes the algorithm which is used to find the kernel), you can specify the version of a custom kernel in KDUMP_KERNELVER. If you set it to foo, then the kernel located in /boot/vmlinuz-foo or /boot/vmlinux-foo (in that order on platforms that have a vmlinuz file) will be used.

You can specify the command line used to boot the Kdump kernel. Normally the boot command line is used, minus settings that are not relevant for Kdump (like the crashkernel parameter) plus some settings needed by Kdump (see the manual page kdump(5)). To specify additional parameters, use KDUMP_COMMANDLINE_APPEND. If you know what you are doing and you want to specify the entire command line, set KDUMP_COMMANDLINE.

Element

Value

Description

chroot

0 / 1

A value of 1 means that the DHCP server must be jailed in a chroot.

start_service

0 / 1

Set this to 1 to enable the DHCP server (that is, run it on system startup).

use_ldap

0 / 1

If set to 1, the settings will be stored in LDAP instead of native configuration files.

other_options

Text

String with parameters that will be passed to the DHCP server executable when started. For example, use "-p 1234" to listen on a non-standard 1234 port. For all possible options, consult the dhcpd manual page. If left blank, default values will be used.

allowed_interfaces

List

List of network cards in which the DHCP server will be operating. See the example below for the exact format.

settings

List

List of settings to configure the behavior of the DHCP server. The configuration is defined in a tree-like structure where the root represents the global options, with subnets and host nested from there. The children, parent_id and parent_type properties are used to represent that nesting. See the example below for the exact format.

4.37 SUSE Firewall

SUSE Firewall can be configured using the firewall resource. All the properties in this resource are optional and all of them are of type text (except the boolean start_firewall and enable_firewall properties).

4.37.1 General Firewall Configuration

The following properties are intended to configure the general settings of SUSE Firewall. Most of them are a direct representation of the corresponding setting at /etc/sysconfig/SuSEfirewall2. Check the comments in that file for further information.

Attribute

Value

Description

start_firewall

Boolean

Whether SUSE Firewall should be started right after applying the configuration.

enable_firewall

Boolean

Whether SUSE Firewall should be started on every system startup.

FW_LOG_ACCEPT_ALL

yes / no

Log every accepted package. If set to "yes" the value of FW_LOG_ACCEPT_CRIT becomes irrelevant.

FW_LOG_ACCEPT_CRIT

yes / no

Log accepted critical packages.

FW_LOG_DROP_ALL

yes / no

Log every dropped package. If set to "yes" the value of FW_LOG_DROP_CRIT becomes irrelevant.

FW_LOG_DROP_CRIT

yes / no

Log dropped critical packages.

FW_ALLOW_PING_FW

yes / no

Allow the firewall to reply to ICMP echo requests.

FW_MASQUERADE

yes / no

Used to enable network masquerading, which allows to transparently redirect ports from one interface in the external zone to ports of another interface in a different zone. Masquerading needs at least one external interface and one other (not external) interface. Since routing is needed for masquerading, the values of this property and FW_ROUTE are connected.

FW_FORWARD_MASQ

Space delimited list of rules

Rules for network masquerading, with each rule following this format: source_network,ip_to_forward_to,protocol,port[,redirect_port,[destination_ip]]

FW_FORWARD_ALWAYS_INOUT_DEV

Space separated list of interface names

Bridge interfaces without IP address.

FW_IPSEC_TRUST

yes / no / int /ext / dmz

Trust level of IPsec packets.

FW_LOAD_MODULES

Space delimited list

Additional kernel modules to load at startup.

FW_ROUTE

yes / no

Whether routing between external, dmz and internal network should be activated. Related to FW_MASQUERADE.

FW_PROTECT_FROM_INT

yes / no / notrack

Whether to protect the firewall from the internal network.

4.37.2 Firewall Zones Configuration

The configuration of SUSE Firewall is based on the existence of three network zones. The behavior of each zone can be tweaked in several ways. Therefore, there are many almost equivalent AutoYaST properties that differ only by name and the zone to which they apply. For example, FW_DEV_DMZ for the demilitarized zone, FW_DEV_EXT for the external zone and FW_DEV_INT for the internal one.

Attributes

Value

Description

FW_ALLOW_FW_BROADCAST_{DMZ/EXT/INT}

yes / no

Allow IP broadcasts in that zone.

FW_CONFIGURATIONS_{DMZ/EXT/INT}

Space delimited list

Services that should be accessible from that zone.

FW_DEV_{DMZ/EXT/INT}

Space delimited list

Name of the interfaces that are considered to belong to the zone. The special keyword "any" means that packets arriving on interfaces not explicitly configured as int, ext or dmz will be considered to belong to this zone.

FW_IGNORE_FW_BROADCAST_{DMZ/EXT/INT}

yes / no

Suppress logging of dropped broadcast packets. Useful if you do not allow broadcasts on a LAN interface.

FW_SERVICES_ACCEPT_{DMZ/EXT/INT}

Space separated list of rules

Services to allow. Each rule following the format net,protocol[,dport[,sport[,flags]]]. For example, "0/0,tcp,22".

FW_SERVICES_ACCEPT_RELATED_{DMZ/EXT/INT}

Space delimited list of rules

Services to allow that are considered RELATED by the connection tracking engine. Format of each rule: net,protocol[,sport[,dport]]. For example, to allow Samba broadcast replies marked as related by nf_conntrack_netbios_ns from a certain network: "192.168.1.0/24,udp,137".

FW_SERVICES_{DMZ/EXT/INT}_IP

Space separated list

Which IP services should be accessible from the zone. Every entry in the list can be a port, a port range or a well known protocol name. This setting has precedence over FW_SERVICES_ACCEPT_*.

FW_SERVICES_{DMZ/EXT/INT}_RPC

Space delimited list

RPC services that should be accessible from the zone. This setting has precedence over FW_SERVICES_ACCEPT_*.

FW_SERVICES_{DMZ/EXT/INT}_TCP

Space separated list

Which TCP services should be accessible from the zone. Every entry in the list can be a port, a port range or a well known protocol name. This setting has precedence over FW_SERVICES_ACCEPT_*.

FW_SERVICES_{DMZ/EXT/INT}_UDP

Space separated list

Which UDP services should be accessible from the zone. Every entry in the list can be a port, a port range or a well known protocol name. This setting has precedence over FW_SERVICES_ACCEPT_*.

In addition to the core component configuration, like network authentication and security, AutoYaST offers a wide range of hardware and system configuration options, the same as available by default on any system installed manually and in an interactive way. For example, it is possible to configure printers, sound devices, TV cards and any other hardware components which have a module within YaST.

Any new configuration options added to YaST will be automatically available in AutoYaST.

4.38.1 Printer

AutoYaST support for printing is limited to basic settings defining how CUPS is used on a client for printing via the network.

There is no AutoYaST support for setting up local print queues. Modern printers are usually connected via USB. CUPS accesses USB printers by a model-specific device URI like usb://ACME/FunPrinter?serial=1a2b3c. Usually it is not possible to predict the correct USB device URI in advance, because it is determined by the CUPS back-end usb during runtime. Therefore it is not possible to set up local print queues with AutoYaST.

Basics on how CUPS is used on a client workstation to print via network:

On client workstations application programs submit print jobs to the CUPS daemon process (cupsd). cupsd forwards the print jobs to a CUPS print server in the network where the print jobs are processed. The server sends the printer specific data to the printer device.

If there is only a single CUPS print server in the network, there is no need to have a CUPS daemon running on each client workstation. Instead it is simpler to specify the CUPS server in /etc/cups/client.conf and access it directly (only one CUPS server entry can be set). In this case application programs that run on client workstations submit print jobs directly to the specified CUPS print server.

Example 4.62, “Printer configuration” shows a printer configuration section. The cupsd_conf_content entry contains the whole verbatim content of the cupsd configuration file /etc/cups/cupsd.conf. The client_conf_content entry contains the whole verbatim content of /etc/cups/client.conf. The printer section contains the cupsd configuration but it does not specify whether the cupsd should run.

Example 4.62: Printer configuration
  <printer>
    <client_conf_content>
      <file_contents><![CDATA[
... verbatim content of /etc/cups/client.conf ...
]]></file_contents>
    </client_conf_content>
    <cupsd_conf_content>
      <file_contents><![CDATA[
... verbatim content of /etc/cups/cupsd.conf ...
]]></file_contents>
    </cupsd_conf_content>
  </printer>
Note
Note: /etc/cups/cups-files.conf

With release 1.6 the CUPS configuration file has been split into two files: cupsd.conf and cups-files.conf. As of SUSE Linux Enterprise Server 12 SP5, AutoYaST only supports modifying cupsd.conf since the default settings in cups-files.conf are sufficient for usual printing setups.

4.38.2 Sound devices

An example of the sound configuration created using the configuration system is shown below.

Example 4.63: Sound configuration
<sound>
  <autoinstall config:type="boolean">true</autoinstall>
  <modules_conf config:type="list">
    <module_conf>
      <alias>snd-card-0</alias>
      <model>M5451, ALI</model>
      <module>snd-ali5451</module>
      <options>
        <snd_enable>1</snd_enable>
        <snd_index>0</snd_index>
        <snd_pcm_channels>32</snd_pcm_channels>
      </options>
    </module_conf>
  </modules_conf>
  <volume_settings config:type="list">
    <listentry>
      <Master config:type="integer">75</Master>
    </listentry>
  </volume_settings>
</sound>

4.39 Importing SSH Keys and Configuration

YaST allows to import SSH keys and server configuration from previous installations. The behavior of this feature can also be controlled through an AutoYaST profile.

Example 4.64: Importing SSH Keys and Configuration from /dev/sda2
<ssh_import>
  <import config:type="boolean">true</import>
  <copy_config config:type="boolean">true</copy_config>
  <device>/dev/sda2</device>
</ssh_import>

Attributes

Value

Description

import

true / false

SSH keys will be imported. If set to false, nothing will be imported.

copy_config

true / false

Additionally, SSH server configuration will be imported. This setting will not have effect if import is set to false.

device

Partition

Partition to import keys and configuration from. If it is not set, the partition which contains the most recently accessed key is used.

4.40 Configuration Management

AutoYaST allows delegating part of the configuration to a configuration management tool like Salt:

  • AutoYaST takes care of system installation (partitioning, network setup, etc.)

  • System configuration can be delegated to a configuration management tool

This module configures the connection to a configuration management tool and uploads SSH keys which are needed for establishing connections. At the end of the installation, the configuration management Master will be contacted to retrieve state files and other resources.

Example 4.65: Configuring Salt Manager
<configuration_management>
    <type>salt</type>
    <master>linux-addc</master>
    <auth_attempts config:type="integer">5</auth_attempts>
    <auth_time_out config:type="integer">10</auth_time_out>
    <keys_url>http://keys.example.de/keys</keys_url>
</configuration_management>

Attributes

Value
