When you click
, you can choose one of the following actions:NOTE:YaST cannot select pre-existing partitions for deletion.
For Novell Linux Point of Service servers, all partitions should be formatted with a journaling file system (ext3) with the exception of the swap partition, where swap should be selected. Table 2-2 provides a base guideline of the size requirements for the Novell Linux Point of Service directories.
Table 2-2 Size guidelines for Novell Linux Point of Service directories
* These directories will grow during production and should be as large as possible.
For more detailed information about partitioning, refer to “Expert Partitioning with YaST” in Chapter 1 of the SUSE Linux Enterprise Server Installation and Administration Guide.
Figure 2-8 shows the Software Selection screen, which lets you select the software packages to be installed on the server.
Figure 2-8 Software Selection screen
The Minimum system includes the core operating system with various services but without any graphical user interface. The machine can only be operated using ASCII consoles. This system type is especially suitable for server scenarios that require little direct user interaction.
The Minimuim graphical system (without KDE) includes The X Window System* and a basic window manager. It lets you run programs that have their own graphical user interface. This option is for those who do not want the KDE desktop or for machines with insufficient disk space for a desktop environment.
Depending on what type of Novell Linux Point of Service server you are installing, you will select one of these two options:
Table 2-3 identifies the software selection options you should select to create each server.
Table 2-3 Software selections for Novell Linux Point of Service servers
To add or remove individual packages from one of the default software selections:
Select one of the default software selections as a starting point for your software selection.
Click
.The YaST Package Manager screen appears, as shown in Figure 2-9.
Figure 2-9 YaST Package Manager.
The Filter box is located at the top left under the menu bar. The default filter is Selections, which groups program packages by function, such as Image Building System or Administration and Branch Server. The Package window lists the individual packages included in each package group. The package groups and individual packages that are included in the current software selection are preselected.

to verify that you have selected all the packages required to run the selected options.IMPORTANT:If you selected Minimum System instead of Minimum Graphical System as the base system, you are asked to resolve a dependency for the GL graphics subsystem when you add the NLPOS Branch and Admin Server Minimum System package. We recommend that you select the MesaSoft package.
Click
to add the selected packages to the installation.YaST informs you of packages that it has automatically added to the software selection to resolve dependences.
Click
to return to the Installation Settings screen.Figure 2-10 shows the Boot Loader Setup screen, which provides a suggested boot configuration for your system. In most cases, you can leave these settings unchanged. However, if you need a custom setup, you can modify the proposal for your system.
Figure 2-10 Boot Loader Setup screen
One possibility is to configure the boot mechanism to rely on a special boot floppy. Although this has the disadvantage that it requires the floppy to be in the drive when booting, it leaves an existing boot mechanism untouched. Normally this should not be necessary because YaST can configure the boot loader to boot existing operating systems as well. Another possibility with the configuration is to change the location of the boot mechanism on the hard disk.
For detailed information about creating a custom boot configuration, see “Configuring the Boot Loader with YaST” in Chapter 8 of the SUSE LINUX Enterprise Server Installation and Administration Guide.
The Clock and Time Zone Configuration screen shown in Figure 2-11 allows you to set the clock and time zone for the server.
Figure 2-11 Clock and Time Zone Configuration screen

To change the system time and date, click
, make the desired setting, and then click .To set the hardware clock to UTC or local time, click the
drop-down menu. In general, you can choose UTC (Universal Time Coordinated) for servers that have only Linux installed. UTC corresponds to GMT (Greenwich Mean Time) and allows Linux to switch from standard time to daylight saving time and back automatically. Choose Local Time for servers that have other operating systems installed. When finished, click .The Language Selection screen shown in Figure 2-12 allows you to change the language on the current system. The language selected in YaST applies to the entire system, including YaST and the desktop environment (KDE or GNOME). You can also slick to set the locale setting for the root user and to specify whether or not to use UTF-8 encoding.
NOTE:Currently, Novell Linux Point of Service is available only in English; therefore, the language selection does not affect the Novell Linux Point of Service scripts or utilities.
Figure 2-12 Language Selection screen.
IMPORTANT:If you change the Language setting after installing Novell Linux Point of Service, you must copy over the RPMs required to support the desktop (KDE or GNOME) you are running on the Administration or Branch Server and modify the system language file. For more information, see Section B.1, Changing the Language Selection.
Click Figure 2-13.
to view the Language Details screen shown inFigure 2-13 Language Details screen
Click the
drop-down menu to select the desired setting.NOTE:The value of the LC_CTYPE variable in the /etc/sysconfig/language file is adopted for the user root. This variable sets the localization for language-specific function calls. If the value is set to Yes, the user root has the same language settings as the local user. If the value is set to No, the language settings for the user root are not affected by the language selection.
Click the
option if you want this server to use UTF-8 encoding for multi-national language support.When finished, click
.Figure 2-14 shows the Set Default Runlevel screen, which lets you set the runlevel to be used when the server is booted.

Usually you select the standard runlevel 5, which offers multiuser mode, network access, and the graphical user interface (X Window System). If you encounter problems with a particular service (X or network), you can boot the system to a lower runlevel to repair the service. You can select from the following options:
WARNING:Incorrect settings for runlevels and system services can render your system useless. To retain the operability of your system, consider the possible consequences before modifying any of these settings.
Click
to apply your setting.After you have accepted your selections in the Installation Settings screen, YaST proceeds with the Base Installation which includes partitioning the hard drive, setting the system language, applying the installation settings, and copying the files from the NLPOS and SLES 9 CDs to disk.
The system then reboots and YaST starts again for the Configuration portion of the installation.
The Root Password screen shown in Figure 2-15 prompts you to enter the password for the root user. For verification purposes, the password must be entered twice.
WARNING:After the root password is entered, it cannot be retrieved. Therefore, we recommend you make a record of the root password and store it in a secure location.
Figure 2-15 Root Password screen
The name of the superuser, or administrator of the system, is root. Unlike regular users, which may or may not have permission to do certain things on the system, root has unlimited power to do anything: change the system configuration, install programs, and set up new hardware. If users forget their passwords or have other problems with the system, root can help. The root account should only be used for system administration, maintenance, and repair. Logging in as root for daily work is not recommended because a single mistake could lead to the irretrievable loss of many system files.
