The YaST sysconfig dialog is split into three parts. The left part of the dialog shows a
tree view of all configurable variables. When you select a variable, the right part displays
both the current selection and the current setting of this variable. Below, a third window
displays a short description of the variable's purpose, possible values, the default value,
and the actual configuration file from which this variable originates. The dialog also
provides information about which configuration script is executed after changing the
variable and which new service is started as a result of the change. YaST prompts you
to confirm your changes and informs you which scripts will be executed after you leave
the dialog by selecting Finish. Also select the services and scripts to skip for now, so
they are started later. YaST applies all changes automatically and restarts any services
involved for your changes to take an effect.
17.3.2 Changing the System Configuration
Manually
To manually change the system configuration, proceed as follows
1 Become root.
2 Bring the system into single user mode (runlevel 1) with init 1.
3 Change the configuration files as needed with an editor of your choice.
If you do not use YaST to change the configuration files in /etc/sysconfig,
make sure that empty variable values are represented by two quotation marks
(KEYTABLE="") and that values with blanks in them are enclosed in quotation
marks. Values consisting of one word only do not need to be quoted.
4 Execute SuSEconfig to make sure that the changes take effect.
5 Bring your system back to the previous runlevel with a command like init
default_runlevel. Replace default_runlevel with the default run-
level of the system. Choose 5 if you want to return to full multiuser with network
and X or choose 3 if you prefer to work in full multiuser with network.
This procedure is mainly relevant when changing systemwide settings, such as the
network configuration. Small changes should not require going into single user mode,
