3.12 Installation Settings

After a thorough system analysis, YaST presents reasonable suggestions for all installation settings. Basic settings can be changed in the Overview tab, advanced options are available on the Experts tab. To modify the suggestions, either click Change and select the category to change or click on one of the headlines. After configuring any of the items presented in these dialogs, you are always returned to the summary window, which is updated accordingly.

HINT: Resetting the changes to default values

You can reset all changes to the defaults by clicking Change > Reset to Defaults. YaST then shows the original proposal again.

3.12.1 Overview

The options that sometimes need manual intervention in common installation situations are presented in the Overview tab. Modify Partitioning, Software selection and Locale settings here.

Keyboard Layout

To change the keyboard layout, select Keyboard Layout. By default, the layout corresponds to the language chosen for installation. Select a keyboard layout from the list. Use the Test field at the bottom of the dialog to check if you can enter special characters of that layout correctly. Find more information about changing the keyboard layout in Section 8.4.10, Keyboard Layout. When finished, click Accept to return to the installation summary.

On the IBM System z platforms, the installation is performed from a remote terminal. The host as such has no keyboard or mouse locally connected to it.

Partitioning

In most cases, YaST proposes a reasonable partitioning scheme that can be accepted without change. YaST can also be used to customize the partitioning, but only experienced users should change partitioning.

When you select the Partitioning for the first time, the YaST partitioning dialog displays the proposed partition settings. To accept these settings, click Accept Proposal.

To make small changes in the proposal, select Base Partition Setup on This Proposal and adjust partitioning in the next dialog. For a completely different partitioning, select Create Custom Partition Setup. In the next dialog, choose a specific disk to partition or Custom Partitioning if you want to have access to all disks. For more information about custom partitioning, refer to Section 8.5.7, Using the YaST Partitionerthe SUSE Linux Enterprise Server documentation. The YaST partitioner also provides a tool for LVM creation. To create an LVM proposal, select Create LVM Based Proposal. See Section 7.1, LVM Configuration for more information on LVM.

NOTE: Using Minidisks in z/VM

If SUSE Linux Enterprise Server is installed on minidisks in z/VM, which reside on the same physical disk, the access path of the minidisks (/dev/disk/by-id/) is not unique but rather the ID of the physical disk. So if two or more minidisks are on the same physical disk, they all have the same ID.

To avoid problems when mounting the minidisks, always mount them either "by path" or "by UUID".

Software

SUSE Linux Enterprise contains a number of software packages for various application purposes. Click Software in the suggestion window to start the software selection and modify the installation scope according to your needs. Select your pattern from the list in the middle and see the description in the right part of the window. Each pattern contains a number of software packages needed for specific functions (e.g. Multimedia or Office software). For a more detailed selection based on software packages to install, select Details to switch to the YaST Software Manager. See Figure 3-5.

Figure 3-5 Installing and Removing Software with the YaST Software Manager

You can also install additional software packages or remove software packages from your system at any time later. For more information, refer to Section 8.3.1, Installing and Removing Software.

NOTE: Default Desktop

The default desktop of SUSE Linux Enterprise is GNOME. To install KDE, click Software and select KDE Desktop Environment from Graphical Environments.

Language

To change the system language or to configure support for secondary languages, select Language. Select a language from the list. The primary language is used as the system language. Choose a secondary languages to be able to switch to one of these languages at any time without having to install additional packages. For more information, see Section 8.5.15, Language Selection.

3.12.2 Expert

If you are an advanced user and want to configure booting or change the time zone or default runlevel, select the Expert tab. It shows the following additional entries not contained on the Overview tab:

System

This dialog presents all the hardware information YaST could obtain about your computer. Select any item in the list and click Details to see detailed information about the selected item. Advanced users can also change the PCI ID setup and Kernel Settings by choosing System Settings.

Add-On Products

The added source for add-on media appears in the overview. Before you start the installation of the SUSE Linux Enterprise, add, remove, or modify add-on products here if needed.

Booting

This module cannot be used to configure the boot loader (zipl) on the IBM System z platforms.

YaST proposes a boot configuration for your system. Normally, you can leave these settings unchanged. However, if you need a custom setup, modify the proposal for your system. For information, see Section 21.3, Configuring the Boot Loader with YaST.

Time Zone

This is the same as the configuration shown earlier in Section 3.11, Clock and Time Zone.

Default Runlevel

SUSE Linux Enterprise can boot to different runlevels. Normally there should be no need to change anything here, but if necessary, set the default runlevel with this dialog. Refer to Section 20.2.3, Configuring System Services (Runlevel) with YaST for information about runlevel configuration.
