The SUSE LINUX Boot Concept
1. Bring the system into single user mode (runlevel 1) with init 1.
2. Change the configuration files as needed. This can be done using an
editor of your choice or with the sysconfig editor of YaST (refer to
Section 11.7).
Caution
Manual Changes to the System Configuration
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 quota-
tion marks. Values consisting of one word only do not need
to be quoted.
Caution
3. Execute SuSEconfig to make sure that the changes take effect. If you
have changed the configuration files with YaST, this is done automati-
cally.
4. Bring your system back to the previous runlevel with a command like
init 3 (replace 3 with the previous runlevel).
This procedure is mainly relevant when changing system-wide settings
(such as the network configuration). Small changes should not require go-
ing into single user mode, but you could still do so to make absolutely sure
all the programs concerned are correctly restarted.
Note
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.
Note
11.7 The YaST sysconfig Editor
The files in which the most important SUSE LINUX settings are stored are
located in the /etc/sysconfig/ directory. The sysconfig editor presents
