Starting and Stoping Services: insserv
Starting and Stoping Services
SuSE is using insserv to control the
runlevel links in an automatic fashion. This section tries to address
questions related to creating and maintaing runlevel links.
- 1. How can I start services at boot time ?
- 2. Why do my runlevel symlinks change order ?
- 3. I can't find chkconfig where is it ?
- 4. How can I stop hwscan from starting at boot time ?
How can I start services at boot time ?
- To start a service:
$ insserv named
- To stop a service from starting:
$ insserv -r named
You can also use

Have a look at insserv(8) manual page for in detail explanations.

Insserv - Enable an installed system init script
Enables an installed system init script (`boot
script') by reading the comment header of the script,
### BEGIN INIT INFO
# Provides: boot_facility_1 [ boot_facility_2 ...]
# Required-Start: boot_facility_1 [ boot_facility_2 ...]
# Required-Stop: boot_facility_1 [ boot_facility_2 ...]
# Default-Start: run_level_1 [ run_level_2 ...]
# Default-Stop: run_level_1 [ run_level_2 ...]
# Description: multiline_description
### END INIT INFO
and calculating the dependencies between all scripts.
If you are interested in making your own init script for a custom program to
start at boot time look at /etc/init.d/skeleton. You
can use this example to create your own.
Why do my runlevel symlinks change order ?
"insserv", is changing the run level links. Every time a package
including an init script is being installed, it calls insserv in its
%post section to install the required run level links. Have a look at
the insserv(8) and init.d(7) man pages. Probably your init script is
lacking the required comments in the header that determine the
default run levels and startup dependencies (as specified by the
Have a look at
SuSE Package Conventions document if you are creating your
own rpms or for a deeper understanding of SuSE RPM internals. Note
that this document is still work in progress...
I can't find chkconfig where is it ?
The equivalent is insserv, refer to the previous question for
detailed info about man pages and other explanations.
chkconfig - enable or disable system services
chkconfig -t|--terse [names]
chkconfig -s|--set [name state]
chkconfig -e|--edit [names]
chkconfig -l|--list [--deps] [names]
chkconfig -a|--add [names]
chkconfig -d|--del [names]
chkconfig is used to manipulate the runlevel links at boot time
(see init.d(7)). It can be thought of as a frontend to insserv(8).
Chkconfig can run in six different modes: terse list mode, set
mode, edit mode, list mode, add mode and delete mode. The last three
modes were added for compatibility reasons
How can I stop hwscan from starting at boot time ?
Fire up YAST
Select "Runlevel Editor"
Select "Runlevel Properties"
Select (from list) "hwscan"
Select "Disable the service"
An alternative procedure is as follows
It's a service called "hwscan", started from the Links in
/etc/init.d/rcX.d where X is your runlevel. To see in which runlevels
your script is invoked :
# chkconfig -l script
Normally you could remove the scripts with:
# insserv -r script
in your case:
# insserv -r hwscan
