In the traditional sense, when we want to include a new service at boot time, we looked into the /etc/init.d/ directory and figure out where to put it.  (I tend to look and figure it out as it changes over the years).

In many other distribution, they provide various ways to do this and to ensure that it is correctly configured.  In SuSE and OpenSuSE, they provided the command insserv for this purpose.

# insserv –r hwscan

If you would like to stop the scanning of hardware configuration at boot time.  Normally, this is turned on but when you have the server configured and running optimally, you may want to disable it to ensure a faster boot up time.  To start it again at boot up time, just

# insserv hwscan

Of course, YAST also provide this, go to YaST Control Center –> System –> System Services (Runlevel).

Where you can enable/disable the services.
