16.3.2 Changing the System Conguration

Manually

To manually change the system conguration, proceed as follows

Become root.

Bring the system into single user mode (runlevel 1) with telinit 1.

Change the conguration les as needed with an editor of your choice.

If you do not use YaST to change the conguration les 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.

Execute SuSEconfig to make sure that the changes take effect.

Bring your system back to the previous runlevel with a command like telinit

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 conguration. 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: Conguring Automated System Conguration

To disable the automated system conguration by SuSEcong, set the variable

ENABLE_SUSECONFIG in /etc/sysconfig/suseconfig to no. Do not

disable SuSEcong if you want to use the SUSE installation support. It is also

possible to disable the autoconguration partially.
