Deploying SUSE Linux Enterprise Products with SUSE Manager on IBM PowerVM

First, you need to perform several actions related to the IBM PowerVM architecture (refer also to the IBM documentation at https://www.ibm.com/support/knowledgecenter/ ):

When the YaST installation tool from SUSE Linux Enterprise Server appears, subscribe with the correct SUSE Customer Center (SCC) registration code (“SUSE Linux Enterprise Server for IBM POWER”). Collect your registration codes from the SCC portal site at https://scc.suse.com.

Now choose to add the SUSE Manager Server extension as shown on the screen below, and enter Next:

Figure 1: YaST Installation - Extensions and Module Selection #

  

Accept the SUSE End User License Agreement (EULA) and enter Next:

Figure 2: YaST Installation - SUSE End User License Agreement #

  

Provide the correct registration code delivered with your SUSE Manager subscription, and enter Next:

Figure 3: YaST Installation - SUSE Manager Registration Code #

  

No additional Add-On Product needs to be installed. Skip this screen and enter Next:

Figure 4: YaST Installation - Add-On Product #

  

The next screen provides the partitioning options:

Figure 5: YaST Installation - Partitioning Options #

  

Select Expert Partitioner:

Figure 6: YaST Installation - Expert Partitioner #

  

Execute Rescan Devices to clear the auto-suggested partitioning:

Figure 7: YaST Installation - Rescan Devices #

  

In the particular scenario at hand, a reinstallation has been performed. In this case, follow the steps below. If partitioning and/or LVM settings are already present, choose to import these settings into the installer, and select Import Mount Points:

Figure 8: YaST Installation - Import Mount Points #

  

Note: Fresh Installation

If you perform an installation from scratch, configure your partitions and LVM settings following the recommendations below:

Minimum 100 GB for root / partition

Minimum 50 GB for /var/lib/pgsql

Minimum 50 GB per SUSE product and 100 GB per Red Hat product for /var/spacewalk

When you are finished, continue with the partitioning step, and enter Next:

Figure 9: YaST Installation - Suggested Partitioning #

  

Provide the correct time zone settings, and confirm them with Next:

Figure 10: YaST Installation - Clock and Time Zone #

  

At this stage you can choose to skip the creation of an initial user. Enter Next:

Figure 11: YaST Installation - Local User #

  

Verify the settings overview and make further changes or customizations where needed. Start the installation with Install:

Figure 12: YaST Installation - Installation Settings #

  

After the installation is finished, verify whether all aspects of the operating system have been installed correctly.

Important: DNS

After the installation make sure you configure your hosts DNS settings and add an entry to DNS. This ensures that the host name can be correctly resolved.

Open an SSH session to the new SUSE Manager host and start YaST:

# yast2 susemanager_setup

Choose to configure SUSE Manager from scratch:

Figure 13: YaST Installation - Setting up SUSE Manager #

  

Enter a correct administrator e-mail address:

Figure 14: YaST Installation - E-mail Address #

  

Provide details for the certificate generation:

Figure 15: YaST Installation - Certificate Generation #

  

Provide database authentication settings:

Figure 16: YaST Installation - Database Settings #

  

Provide your SUSE Manager SCC organization user name and password:

Figure 17: YaST Installation - SCC Settings #

  

Perform an authentication test toward the SUSE Customer Center:

Figure 18: YaST Installation - Test Details #

  

Confirm to run the setup process with Yes:

Figure 19: YaST Installation - Setup Process Confirmation #

  

Now the setup process is started:

Figure 20: YaST Installation - Write Settings #

  

Wait until the setup process is completed. Then enter Finish:

Figure 21: YaST Installation - Setup Completed #

  

Verify that you can access the new SUSE Manager URL using a browser.

Important:

At time of writing this document, in SUSE Linux Enterprise Server 12 SP3 a minor workaround needs to be applied to the Apache configuration file to use spacewalk:

Add the following file with the following line of content:

# vi /etc/apache2/conf.d/zipp-fix.conf
HttpProtocolOptions Unsafe

Restart Apache to activate the change:

# systemctl restart apache2.service

After the SUSE Manager setup is finished, you must create your organization on the SUSE Manager Web user interface.

Provide all the requested details including an initial administrator user and password:

Figure 22: SUSE Manager Web UI - Create Organization #

  

Confirm with Create Organization. The following message appears on the screen:

Figure 23: SUSE Manager Web UI - Organization Created Successfully #

  

Navigate to the Setup Wizard in the left pane:

Figure 24: SUSE Manager Web UI - Setup Wizard #

  

Select the Organization Credentials tab:

Figure 25: SUSE Manager Web UI - Organization Credentials #

  

Click Add a new credential:

Figure 26: SUSE Manager Web UI - Add Credential #

  

Enter your correct organization credentials from the SCC portal and save them:

Figure 27: SUSE Manager Web UI - Edit Credentials #

  

Now navigate to the SUSE Products tab and select the SUSE products you need. In this example, SUSE Linux Enterprise Server for SAP Applications 12 SP3 has been selected:

Figure 28: SUSE Manager Web UI - SUSE Products #

  

Do not forget to also check the sub-channels you need for each product:

Figure 29: SUSE Manager Web UI - Sub-Channels #

  

When your selection is done, confirm it with Add products:

Figure 30: SUSE Manager Web UI - Add Products #

  

Navigate to Manager Configuration in the left pane, and select Bare-metal systems as indicated below:

Figure 31: SUSE Manager Web UI - Bare-metal Systems #

  

Now enable Bare-metal systems; click the green box Enable adding to this organization:

Figure 32: SUSE Manager Web UI - Enable Bare-metal Systems #

  

The following section describes how to create the software channel hierarchy.

Log on as root using SSH. Install the spacewalk-utils package with the following command:

# zypper install spacewalk-utils

Check whether the available channels correspond with selections made before:

# spacewalk-manage-channel-lifecycle  --list-channels

# spacewalk-repo-sync --channel ibm-dlpar-utils-sap-sp3
…

Synchronize the base channel :
# spacewalk-repo-sync --channel sle12-sp2-sap-pool-ppc64le
...

# spacewalk-repo-sync --channel sle12-sp3-sap-pool-ppc64le
…

In the specific setup at hand, the lifecycle phases are limited to “dev” and “prod” (“test” has been removed).

vi ~/.spacewalk-manage-channel-lifecycle/settings.conf
phases = dev, prod
exclude channels =

This can be customized as required, which means you can add and remove phases at this stage of the procedure.

Generate the “dev” channels by promoting the SUSE channels. The same command is used to fully synchronize the “dev” channels with the online repositories:

The same steps need to be performed for any additional product or version:

# spacewalk-manage-channel-lifecycle -c sle12-sp3-sap-pool-ppc64le –promote
…

# spacewalk-manage-channel-lifecycle -c dev-sle12-sp3-sap-pool-ppc64le –promote
…

For all of the -ibm-dlpar-utils- child channels, deactivate the GPG check as it requires an external GPG key from IBM. To do so, navigate to Software in the left pan. Then go to Manage Software Channels and choose Overview:

Figure 33: SUSE Manager Web UI - Manage Software Channels #

  

A list of all of the -ibm-dlpar-utils- child channels appears:

Figure 34: SUSE Manager Web UI - List of Child Channels #

  

Make sure the check box for Enable GPG Check is not marked:

Figure 35: SUSE Manager Web UI - Enable GPG Check #

  

Alternatively you can download the GPG key locally and configure a local URL.

Optionally you can configure system groups to distinguish different types of systems. In this example the system groups “development” and “production” are configured.

Navigate to Systems on the left pane, and select System Groups:

Figure 36: SUSE Manager Web UI - System Groups #

  

Click Create Group:

Figure 37: SUSE Manager Web UI - Button Create Group #

  

Enter the required information and confirm by clicking Create Group:

Figure 38: SUSE Manager Web UI - Create System Groups #

  

Now you see the newly created groups:

Figure 39: SUSE Manager Web UI - Show System Groups #

  

Navigate to Manager Configuration on the left pane, and select Bootstrap Script.

Figure 40: SUSE Manager Web UI - Menu Manager Configuration #

  

Click the Bootstrap Script tab on top. Enter the required information to create the general client bootstrap script configuration:

Figure 41: SUSE Manager Web UI - Tab Bootstrap Script #

  

Provide the correct Fully-Qualified Domain Name (FQDN) for the SUSE Manager host name.

Now create the activation keys. Navigate to Systems on the left pane and choose Activation Keys:

Figure 42: SUSE Manager Web UI - Activation Keys #

  

Click Create Key:

Figure 43: SUSE Manager Web UI - Button Create Key #

  

Create a universal activation key first:

Figure 44: SUSE Manager Web UI - Universal Key #

  

After that, create a key you will use for the autoinstall procedure. For the example at hand, the “dev” channel has been selected as base channel.

Figure 45: SUSE Manager Web UI - Create Key for “dev” Channel #

  

Click the Child Channels tab on top. The appropriate channels should be linked here:

Figure 46: SUSE Manager Web UI - Child Channels #

  

Click the Packages tab on top, and add the following values as packages:

Figure 47: SUSE Manager Web UI - Packages #

  

Click Update Activation Key.

Now add the development group to this key. Click the Groups tab on top and choose List / Leave:

Figure 48: SUSE Manager Web UI - Groups - List/Leave #

  

Optionally you can also create and add configuration channels.

Perform the same configuration for a prod key:

Figure 49: SUSE Manager Web UI - Create Key for “prod” Channel #

  

You also need to create a bootstrap repository. Use the command:

# mgr-create-bootstrap-repo -c SLES4SAP-12-SP2-ppc64le

Bootstrap scripts are usually generated automatically, but you can manually generate them for each key using the following CLI syntax:

# mgr-bootstrap --activation-keys=1-dev-sle12-sp2-sap-pool-ppc64le --script bootstrap-dev-sle12-sp2-sap-pool-ppc64le.sh --no-up2date --allow-config-actions --allow-remote-commands

# mgr-bootstrap --activation-keys=1-prod-sle12-sp2-sap-pool-ppc64le --script bootstrap-prod-sle12-sp2-sap-pool-ppc64le.sh  --no-up2date --allow-config-actions –allow-remote-commands

The default path where the bootstrap scripts reside is /srv/www/htdocs/pub/bootstrap.

The URL to access the scripts is https://hostname.domain/pub/bootstrap/bootstrap-scriptname.sh.

An already installed SUSE Linux Enterprise Server host can be bootstrapped using the following syntax from that host:

curl -Sks https://hostname.domain/pub/bootstrap/bootstrap-scriptname.sh |  /bin/bash

You can also copy and past the script below and execute it.

The following script blueprint can be used to create a custom bootstrap script. Modify the SUSE Manager host name and the activation key according to your requirements.

Open an SSH session to the SUSE Manager server with X11 Forwarding enabled (on Microsoft Windows, use PuTTY and Xming ):

Figure 50: SUSE Manager Web UI - Administrator Settings #

  

Click the icon for the DHCP server:

Figure 51: SUSE Manager Web UI - Icon DHCP Server #

  

A window appears listing the packages that need to be installed:

Figure 52: SUSE Manager Web UI - Packages to Install #

  

Install the required packages.

Select the interface(s) for the DHCP service and click Next:

Figure 53: SUSE Manager Web UI - DHCP Server Wizard: Card Selection #

  

Provide the global settings and click Next:

Figure 54: SUSE Manager Web UI - DHCP Server Wizard: Global Settings #

  

Provide the information for Dynamic DHCP and click Next:

Figure 55: SUSE Manager Web UI - DHCP Server Wizard: Dynamic DHCP #

  

Now select when and how to start the service:

Figure 56: SUSE Manager Web UI - Start Service #

  

Finish the basic configuration. Continue by customizing the DHCP configuration file manually for bootp netboots.

The example below shows how static netboot and DHCP can be configured:

# vi /etc/dhcpd.conf
option domain-name "[Domain name]";
option domain-name-servers [DNS IP];
option routers [Gateway ip];
default-lease-time 60;
ddns-update-style none;
host [netboot client hostname] {
  hardware ethernet [MAC address lower case];
  fixed-address [client ip];
  next-server [suse manager ip];
  allow bootp;
  server-name "[susemanager FQDN]";
  filename "boot/grub2/powerpc-ieee1275/core.elf";
}
subnet [Network] netmask [Subnet] {
  range dynamic-bootp [range lowest ip] [range highest ip];
  default-lease-time 5;
  max-lease-time 3600;
  filename "boot/grub2/powerpc-ieee1275/core.elf";
  next-server [suse manager server];
  }

Restart the DHCP daemon with the following command:

# systemctl restart dhcpd.service

Add additional host entries for each new LPAR you want to be able to netboot.

Important: IBM Power Systems Firmware

When performing a bootp boot through the IBM Power Systems firmware, a static IP address is used to load the initial boot image. Because of the nature of the SUSE installation tool YaST, the network configuration in the first phase of the SUSE installer will use DHCP to acquire an IP.

To enable Autoinstallation, you first need to create a subdirectory where you copy the contents of the SUSE product installation DVDs:

# mkdir -p /srv/www/htdocs/install/SLES12SP2SAP_PPC64LE
# mount /dev/sr0 /mnt
# cd /mnt
# cp -r * /srv/www/htdocs/install/SLES12SP2SAP_PPC64LE
…

Now navigate to Systems on the left pane. Select Autoinstallation and then Distributions:

Figure 57: SUSE Manager Web UI - Autoinstallation #

  

Add a new distribution:

Figure 58: SUSE Manager Web UI - Create Distribution #

  

Provide the following custom kernel options:

lang=en_US repo=http://[SUMA IP]/ks/dist/dev-sle12-sp2-sap-pool-ppc64le
install=http://[SUMA IP]/ks/dist/dev-sle12-sp2-sap-pool-ppc64le self_update=0
pt.options=+self_update

The “Tree path” is the local path where the SUSE install DVD content resides. The URLs should contain the name of the correct base channel.

Navigate to Autoinstallation Snippets:

Figure 59: SUSE Manager Web UI - Autoinstallation Snippets #

  

“Autoinstallation Snippets” is used to add the bootstrap process to the autoinstallation post-install process. Click Create Snippet:

Figure 60: SUSE Manager Web UI - Create Snippet #

  

Fill in the required information as shown on the screen below:

Figure 61: SUSE Manager Web UI - Kickstart Snippet #

  

In the Contents field, enter the following:

#raw
curl -Sks https://[SUMA FQDN]/pub/bootstrap/bootstrap-dev-sle12sp2-sap.sh |  /bin/bash

zypper ref -y;zypper -n patch -l -y;zypper -n patch -l -y;zypper -n up -l -y
#end raw

This script will automatically execute the bootstrap script and directly perform all patch updates.

You also created a Production snippet “bootstrap-prod-sles12-sp2” which points to the production bootstrap script. This is the custom bootstrap script you created earlier.

Navigate to System on the left pane. Select Autoinstallation” and then Profiles”:

Figure 62: SUSE Manager Web UI - Profiles #

  

Now you can create an autoinstallation profile. Click Upload Kickstart/Autoyast File:

Figure 63: SUSE Manager Web UI - Button Upload Kickstart/Autoyast File #

  

The screen below opens. Provide the required details and an AutoYaST script:

Figure 64: SUSE Manager Web UI - Create Autoinstallation Profile #

  

To create a baseline AutoYaST profile, perform a reference manual install on an LPAR. Configure the Linux installation to the point where you are satisfied and where it can serve as a base setup for new LPARs. Then generate the autoyast.xml file using the command yast2 clone_system.

This AutoYaST file can be used as is. However, for the document at hand, choose to add variables to it to easily customize an installation from the SUSE Manager GUI. Also, add the post install snippet.

Below find “copy and paste” segments of the example profile. These segments indicate where changes need to be or can be applied. Parameterization must be customized in synchronization with the needs of the environment.

      <disklabel>msdos</disklabel>
      <enable_snapshots config:type="boolean">true</enable_snapshots>

…...

…...
</profile>

You used variables to make ad-hoc customization of the AutoYaST profile easy through the SUSE Manager Web interface. As an overview, the following lines are affected in the above profile:

<boot_custom>/dev/disk/by-id/scsi-3$lunserial-part1</boot_custom>
<hostname>$hostname</hostname>
<nameserver>$dns1</nameserver>
<nameserver>$dns2</nameserver>
<nameserver>$dns3</nameserver>
<ipaddr>$ipaddr1</ipaddr>
<netmask>$subnet1</netmask>
<value>$mac1</value>
<gateway>$gateway</gateway>
<address>$ntp1</address>
<address>$ntp2</address>
<device>/dev/mapper/3$lunserial</device>

Now go to the Variables tab and provide the correct values:

Figure 65: SUSE Manager Web UI - Variables #

  

In this particular example a Fibre Channel (FC) connected storage (IBM) is used which can be identified in /dev/disk/by-id and /dev/mapper by its LUN serial number.

Verify that the syntax of the profile and variables is correct by checking the Autoinstallation File tab. It should show the final script where the variables and snippets have been replaced by their values. If this tab presents an error, you might have an issue in your syntax.

At this point you need to access a SUSE Linux Enterprise Server 12 ppc64le host with the same SP and kernel version as the one you want to deploy through autoinstallation. A good possibility is to use the reference installation host where you based the AutoYaST template on.

Here you need to generate the GRUB2 netboot files. Connect via SSH to the host and type the following command:

# grub2-mknetdir –net-directory=/srv/tftpboot

Copy the files to the /root home:

# scp -r /srv/tftpboot/boot/grub2 root@[suse manager host]:/root/

On SUSE Manager, create a custom grub.cfg file to go with these netboot files :

# vi /root/grub2/grub.cfg
with_gfx=0

gfxmode=auto
locale_dir=$prefix/locale
lang=en_US

set default='dev-sle12-sp2-sap-pool-ppc64le:1:IRIS'

insmod gettext

if sleep --interruptible 0 ; then
  timeout=30
fi

menuentry 'dev-sle12-sp2-sap-pool-ppc64le:1:IRIS' --class opensuse --class gnu-linux --class gnu --class os {
insmod http
insmod tftp
set root=tftp,[suma ip]
echo 'Loading kernel ...'
linux /images/dev-sle12-sp2-sap-pool-ppc64le_1_IRIS/linux ksdevice=bootif lang=en_US pt.options=+self_update repo=http://[suma ip]/ks/dist/dev-sle12-sp2-sap-pool-ppc64le install=http://[suma ip]/ks/dist/dev-sle12-sp2-sap-pool-ppc64le self_update=0 textmode=1 autoyast=http://[suma ip]/cblr/svc/op/ks/profile/dev-sle12-sp2-sap-pool-ppc64le:1:IRIS
echo 'Loading initial ramdisk ...'
initrd /images/dev-sle12-sp2-sap-pool-ppc64le_1_IRIS/initrd
}

menuentry 'local' {
  exit
}

submenu 'Other options...' {
 menuentry 'Reboot' {
 reboot
 }

 menuentry 'Exit to Open Firmware' {
 exit
 }
}

You can base this configuration off the auto-generated /srv/tftpboot/grub/grub.cfg.

Cobbler is a Linux installation server that allows for rapid setup of network installation environments (see http://cobbler.github.io/. It is used to generate the content of the /srv/tftpboot path. As it wipes the path every time a synchronization is triggered, you need to put in place the workaround below. This guarantees your custom GRUB files for IBM PowerVM are recopied in the tftpboot directory each time the configuration is resynchronized:

# vi /var/lib/cobbler/triggers/sync/post/grub2.sh
#!/bin/sh
cp -r /root/grub2 /srv/tftpboot/boot/

Note: Example Path

In this example /root/grub2 is only used as an example path to place your base versions of the GRUB configurations. You can choose a different location.

Next, enter the command:

# chmod u+x /var/lib/cobbler/triggers/sync/post/grub2.sh

The Cobbler post-synchronization script now copies the GRUB2 files over to the TFTP boot directory with every synchronization.

You can synchronize Cobbler with the command:

# cobbler sync

Alternatively, you can use the SUSE Manager Web interface. Navigate to Manager Configuration and select Cobbler:

Figure 66: SUSE Manager Web UI - Cobbler #

  

Now run the Cobbler synchronization and click Update:

Figure 67: SUSE Manager Web UI - Cobbler Synchronization #

  

Verify after a synchronization that the following files have been generated:

First collect the following details:

Via the SUSE Manager Web interface, customize the variables for the AutoYaST profile you created earlier using the collected values above. Go to Systems on the left pane, select Autoinstallation”, and then Profile. Choose specific profile and click the Variables tab. Here you can enter the variables.

The LPAR details needed, which you can retrieve from the Hardware Management Console (HMC), are:

Now you have all required details and you can launch the LPAR netboot via the HMC.

Via SSH connection, log in to the correct HMC host. Use the following command to execute the LPAR netboot and immediately open the serial console:

> lpar_netboot -v -f -D -m [MAC] -i -t ent -T off -s auto -d auto -S [SUMA IP] -G [GATEWAY IP] -C [LPAR IP] -K [NETMASK] "[LPAR NAME]" "[LPAR PROFILE]" "[SYSTEM NAME]"; rmvterm -m [SYSTEM NAME] --id [LPAR ID] ; mkvterm -m [SYSTEM NAME] --id [LPAR ID]

Important: Values

Replace the above [...] fields in the command with the following values:

[MAC] = bootp client mac address without ‘:’ separators and in uppercase

[SUMA IP] = SUSE Manager IP

[GATEWAY IP] = default gateway ip

[LPAR IP] = client lpar ip

[NETMASK] = subnet mask

[LPAR NAME] = lpar name as seen on the HMC

[LPAR PROFILE] = default lpar profile configured on the HMC for this LPAR

[SYSTEM NAME] = system name of the power server that hosts the lpar

[LPAR ID] = the LPAR ID number (check the HMC)

If everything is correct, the GRUB menu should load:

Figure 68: GRUB Menu #

  

When the default grub option is loaded, the installation will start automatically and perform all the installation steps.

Figure 69: Performing Installation #

  

If the bootstrap section in the AutoYaST profile was successful, the new host should appear in the “Physical Systems»” list. Navigate to Systems in the left pane, and select Physical Systems.

Figure 70: SUSE Manager Web UI - Physical Systems #

  

All physical systems are listed here:

Figure 71: SUSE Manager Web UI - List of Physical Systems #

  

Your installed host is now be available for use:

Figure 72: SUSE Manager Web UI - Installed Host #

  

SUSE Manager was designed to manage Linux systems across a variety of hardware architectures, hypervisors and container and cloud platforms with a single tool. It helps your enterprise DevOps and IT Operations teams reduce complexity and regain control of your IT assets. It automates Linux server provisioning, patching and configuration for faster, consistent and repeatable server deployment. Thus you can optimize operations and reduce costs. With automated monitoring, tracking, auditing and reporting of your systems, VMs, and containers across your entire IT environment, you can ensure compliance with internal security policies and external regulations.

SUSE Manager 3 is an ideal platform to centralize package repositories and configuration management on many platforms, including IBM Power. Through auto-deployment via AutoYaST and Netboot you can reduce hands-on time needed to perform deployments of new LPARs, reinstalls or even disaster-recovery scenarios without the need of an AIX based Network Install Manager. Also, the methodology displayed in this document allows you to netboot little-endian kernels through GRUB2 which is required to support SUSE Linux Enterprise Server 12 and up on IBM Power.

When you run a production PowerVM environment with applications such as SAP HANA or other ERP or database systems, spread over several PowerVM LPARs (VMs) and physical IBM Power systems, SUSE Manager is tremendously useful to centrally manage Linux software levels and configurations to satisfy the changing requirements posed by the application vendors.

Below we draw your attention to the license under which the articles are published.

Copyright (C) 2000, 2001, 2002 Free Software Foundation, Inc. 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA. Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed.

The purpose of this License is to make a manual, textbook, or other functional and useful document "free" in the sense of freedom: to assure everyone the effective freedom to copy and redistribute it, with or without modifying it, either commercially or non-commercially. Secondarily, this License preserves for the author and publisher a way to get credit for their work, while not being considered responsible for modifications made by others.

This License is a kind of "copyleft", which means that derivative works of the document must themselves be free in the same sense. It complements the GNU General Public License, which is a copyleft license designed for free software.

We have designed this License to use it for manuals for free software, because free software needs free documentation: a free program should come with manuals providing the same freedoms that the software does. But this License is not limited to software manuals; it can be used for any textual work, regardless of subject matter or whether it is published as a printed book. We recommend this License principally for works whose purpose is instruction or reference.

This License applies to any manual or other work, in any medium, that contains a notice placed by the copyright holder saying it can be distributed under the terms of this License. Such a notice grants a world-wide, royalty-free license, unlimited in duration, to use that work under the conditions stated herein. The "Document", below, refers to any such manual or work. Any member of the public is a licensee, and is addressed as "you". You accept the license if you copy, modify or distribute the work in a way requiring permission under copyright law.

A "Modified Version" of the Document means any work containing the Document or a portion of it, either copied verbatim, or with modifications and/or translated into another language.

A "Secondary Section" is a named appendix or a front-matter section of the Document that deals exclusively with the relationship of the publishers or authors of the Document to the Document's overall subject (or to related matters) and contains nothing that could fall directly within that overall subject. (Thus, if the Document is in part a textbook of mathematics, a Secondary Section may not explain any mathematics.) The relationship could be a matter of historical connection with the subject or with related matters, or of legal, commercial, philosophical, ethical or political position regarding them.

The "Invariant Sections" are certain Secondary Sections whose titles are designated, as being those of Invariant Sections, in the notice that says that the Document is released under this License. If a section does not fit the above definition of Secondary then it is not allowed to be designated as Invariant. The Document may contain zero Invariant Sections. If the Document does not identify any Invariant Sections then there are none.

The "Cover Texts" are certain short passages of text that are listed, as Front-Cover Texts or Back-Cover Texts, in the notice that says that the Document is released under this License. A Front-Cover Text may be at most 5 words, and a Back-Cover Text may be at most 25 words.

A "Transparent" copy of the Document means a machine-readable copy, represented in a format whose specification is available to the general public, that is suitable for revising the document straightforwardly with generic text editors or (for images composed of pixels) generic paint programs or (for drawings) some widely available drawing editor, and that is suitable for input to text formatters or for automatic translation to a variety of formats suitable for input to text formatters. A copy made in an otherwise Transparent file format whose markup, or absence of markup, has been arranged to thwart or discourage subsequent modification by readers is not Transparent. An image format is not Transparent if used for any substantial amount of text. A copy that is not "Transparent" is called "Opaque".

Examples of suitable formats for Transparent copies include plain ASCII without markup, Texinfo input format, LaTeX input format, SGML or XML using a publicly available DTD, and standard-conforming simple HTML, PostScript or PDF designed for human modification. Examples of transparent image formats include PNG, XCF and JPG. Opaque formats include proprietary formats that can be read and edited only by proprietary word processors, SGML or XML for which the DTD and/or processing tools are not generally available, and the machine-generated HTML, PostScript or PDF produced by some word processors for output purposes only.

The "Title Page" means, for a printed book, the title page itself, plus such following pages as are needed to hold, legibly, the material this License requires to appear in the title page. For works in formats which do not have any title page as such, "Title Page" means the text near the most prominent appearance of the work's title, preceding the beginning of the body of the text.

A section "Entitled XYZ" means a named subunit of the Document whose title either is precisely XYZ or contains XYZ in parentheses following text that translates XYZ in another language. (Here XYZ stands for a specific section name mentioned below, such as "Acknowledgements", "Dedications", "Endorsements", or "History".) To "Preserve the Title" of such a section when you modify the Document means that it remains a section "Entitled XYZ" according to this definition.

The Document may include Warranty Disclaimers next to the notice which states that this License applies to the Document. These Warranty Disclaimers are considered to be included by reference in this License, but only as regards disclaiming warranties: any other implication that these Warranty Disclaimers may have is void and has no effect on the meaning of this License.

You may copy and distribute the Document in any medium, either commercially or noncommercially, provided that this License, the copyright notices, and the license notice saying this License applies to the Document are reproduced in all copies, and that you add no other conditions whatsoever to those of this License. You may not use technical measures to obstruct or control the reading or further copying of the copies you make or distribute. However, you may accept compensation in exchange for copies. If you distribute a large enough number of copies you must also follow the conditions in section 3.

You may also lend copies, under the same conditions stated above, and you may publicly display copies.

If you publish printed copies (or copies in media that commonly have printed covers) of the Document, numbering more than 100, and the Document's license notice requires Cover Texts, you must enclose the copies in covers that carry, clearly and legibly, all these Cover Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on the back cover. Both covers must also clearly and legibly identify you as the publisher of these copies. The front cover must present the full title with all words of the title equally prominent and visible. You may add other material on the covers in addition. Copying with changes limited to the covers, as long as they preserve the title of the Document and satisfy these conditions, can be treated as verbatim copying in other respects.

If the required texts for either cover are too voluminous to fit legibly, you should put the first ones listed (as many as fit reasonably) on the actual cover, and continue the rest onto adjacent pages.

If you publish or distribute Opaque copies of the Document numbering more than 100, you must either include a machine-readable Transparent copy along with each Opaque copy, or state in or with each Opaque copy a computer-network location from which the general network-using public has access to download using public-standard network protocols a complete Transparent copy of the Document, free of added material. If you use the latter option, you must take reasonably prudent steps, when you begin distribution of Opaque copies in quantity, to ensure that this Transparent copy will remain thus accessible at the stated location until at least one year after the last time you distribute an Opaque copy (directly or through your agents or retailers) of that edition to the public.

It is requested, but not required, that you contact the authors of the Document well before redistributing any large number of copies, to give them a chance to provide you with an updated version of the Document.

You may copy and distribute a Modified Version of the Document under the conditions of sections 2 and 3 above, provided that you release the Modified Version under precisely this License, with the Modified Version filling the role of the Document, thus licensing distribution and modification of the Modified Version to whoever possesses a copy of it. In addition, you must do these things in the Modified Version:

If the Modified Version includes new front-matter sections or appendices that qualify as Secondary Sections and contain no material copied from the Document, you may at your option designate some or all of these sections as invariant. To do this, add their titles to the list of Invariant Sections in the Modified Version's license notice. These titles must be distinct from any other section titles.

You may add a section Entitled "Endorsements", provided it contains nothing but endorsements of your Modified Version by various parties--for example, statements of peer review or that the text has been approved by an organization as the authoritative definition of a standard.

You may add a passage of up to five words as a Front-Cover Text, and a passage of up to 25 words as a Back-Cover Text, to the end of the list of Cover Texts in the Modified Version. Only one passage of Front-Cover Text and one of Back-Cover Text may be added by (or through arrangements made by) any one entity. If the Document already includes a cover text for the same cover, previously added by you or by arrangement made by the same entity you are acting on behalf of, you may not add another; but you may replace the old one, on explicit permission from the previous publisher that added the old one.

The author(s) and publisher(s) of the Document do not by this License give permission to use their names for publicity for or to assert or imply endorsement of any Modified Version.

You may combine the Document with other documents released under this License, under the terms defined in section 4 above for modified versions, provided that you include in the combination all of the Invariant Sections of all of the original documents, unmodified, and list them all as Invariant Sections of your combined work in its license notice, and that you preserve all their Warranty Disclaimers.

The combined work need only contain one copy of this License, and multiple identical Invariant Sections may be replaced with a single copy. If there are multiple Invariant Sections with the same name but different contents, make the title of each such section unique by adding at the end of it, in parentheses, the name of the original author or publisher of that section if known, or else a unique number. Make the same adjustment to the section titles in the list of Invariant Sections in the license notice of the combined work.

In the combination, you must combine any sections Entitled "History" in the various original documents, forming one section Entitled "History"; likewise combine any sections Entitled "Acknowledgements", and any sections Entitled "Dedications". You must delete all sections Entitled "Endorsements".

You may make a collection consisting of the Document and other documents released under this License, and replace the individual copies of this License in the various documents with a single copy that is included in the collection, provided that you follow the rules of this License for verbatim copying of each of the documents in all other respects.

You may extract a single document from such a collection, and distribute it individually under this License, provided you insert a copy of this License into the extracted document, and follow this License in all other respects regarding verbatim copying of that document.

A compilation of the Document or its derivatives with other separate and independent documents or works, in or on a volume of a storage or distribution medium, is called an "aggregate" if the copyright resulting from the compilation is not used to limit the legal rights of the compilation's users beyond what the individual works permit. When the Document is included in an aggregate, this License does not apply to the other works in the aggregate which are not themselves derivative works of the Document.

If the Cover Text requirement of section 3 is applicable to these copies of the Document, then if the Document is less than one half of the entire aggregate, the Document's Cover Texts may be placed on covers that bracket the Document within the aggregate, or the electronic equivalent of covers if the Document is in electronic form. Otherwise they must appear on printed covers that bracket the whole aggregate.

Translation is considered a kind of modification, so you may distribute translations of the Document under the terms of section 4. Replacing Invariant Sections with translations requires special permission from their copyright holders, but you may include translations of some or all Invariant Sections in addition to the original versions of these Invariant Sections. You may include a translation of this License, and all the license notices in the Document, and any Warranty Disclaimers, provided that you also include the original English version of this License and the original versions of those notices and disclaimers. In case of a disagreement between the translation and the original version of this License or a notice or disclaimer, the original version will prevail.

If a section in the Document is Entitled "Acknowledgements", "Dedications", or "History", the requirement (section 4) to Preserve its Title (section 1) will typically require changing the actual title.

You may not copy, modify, sublicense, or distribute the Document except as expressly provided for under this License. Any other attempt to copy, modify, sublicense or distribute the Document is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance.

The Free Software Foundation may publish new, revised versions of the GNU Free Documentation License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. See http://www.gnu.org/copyleft/.

Each version of the License is given a distinguishing version number. If the Document specifies that a particular numbered version of this License "or any later version" applies to it, you have the option of following the terms and conditions either of that specified version or of any later version that has been published (not as a draft) by the Free Software Foundation. If the Document does not specify a version number of this License, you may choose any version ever published (not as a draft) by the Free Software Foundation.
