19.3.2 Changing the System Configuration
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.
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
This procedure is mainly relevant when changing systemwide settings, such as the
network configuration. Small changes should not require going into single user mode,
but you may still do so to make absolutely sure that all the programs concerned are
correctly restarted.
TIP: Configuring Automated System Configuration
To disable the automated system configuration by SuSEconfig, set the variable
ENABLE_SUSECONFIG in /etc/sysconfig/suseconfig to no. Do not
disable SuSEconfig if you want to use the SUSE installation support. It is also
possible to disable the autoconfiguration partially.

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.
