WARNING: Faulty Runlevel Settings May Damage Your System
Faulty runlevel settings may render a system unusable. Before applying your
changes, make absolutely sure that you know their consequences.
19.3 System Configuration via
The main configuration of SUSE Linux Enterprise is controlled by the configuration
files in /etc/sysconfig. The individual files in /etc/sysconfig are only read
by the scripts to which they are relevant. This ensures that network settings, for example,
only need to be parsed by network-related scripts. Many other system configuration
files are generated according to the settings in /etc/sysconfig. This task is per-
formed by SuSEconfig. For example, if you change the network configuration,
SuSEconfig might make changes to the file /etc/host.conf as well, because this
is one of the files relevant for the network configuration. This concept allows most
configurations to be made in one central place without fiddling with different configu-
ration files at different places of the operating system.
There are two ways to edit the system configuration. Either use the YaST sysconfig
Editor or edit the configuration files manually.
19.3.1 Changing the System Configuration
The YaST sysconfig editor provides an easy-to-use front-end to system configuration.
Without any knowledge of the actual location of the configuration variable you need
to change, you can just use the built-in search function of this module, change the value
of the configuration variable as needed, and let YaST take care of applying these
changes, updating configurations that depend on the values set in sysconfig and
restarting services.
