update-alternatives
: managing multiple versions of commands and files Often, there are several versions of the same tool installed on a system. To give administrators a choice and to make it possible to install and use different versions side by side, the alternatives system allows managing such versions consistently.
- 23 Basic networking
Linux offers the necessary networking tools and features for integration into all types of network structures. Network access using a network card can be configured with YaST. Manual configuration is also possible. In this chapter, only the fundamental mechanisms and the relevant network configuration files are covered.

- 25 Graphical user interface
SUSE Linux Enterprise Desktop includes the X.org server, Wayland and the GNOME desktop. This chapter describes the configuration of the graphical user interface for all users.
- 26 Accessing file systems with FUSE
FUSE is the acronym for Filesystem in Userspace. This means you can configure and mount a file system as an unprivileged user. Normally, you need to be
root
for this task. FUSE alone is a kernel module. Combined with plug-ins, it allows you to extend FUSE to access almost all file systems like remote SSH connections, ISO images, and more.- 27 Installing multiple kernel versions
SUSE Linux Enterprise Desktop supports the parallel installation of multiple kernel versions. When installing a second kernel, a boot entry and an initrd are automatically created, so no further manual configuration is needed. When rebooting the machine, the newly added kernel is available as an additional boot parameter.
Using this functionality, you can safely test kernel updates while being able to always fall back to the proven former kernel. To do this, do not use the update tools (such as the YaST Online Update or the updater applet), but instead follow the process described in this chapter.

udev
- 30 Special system features
This chapter starts with information about various software packages, the virtual consoles and the keyboard layout. We talk about software components like
bash
,cron
andlogrotate
, because they were changed or enhanced during the last release cycles. Even if they are small or considered of minor importance, users should change their default behavior, because these components are often closely coupled with the system. The chapter concludes with a section about language and country-specific settings (I18N and L10N).- 31 Using NetworkManager
