When the init process is started, two important stages in the boot process have to be executed. In the first stage, all the important services must be started. These are hardware-related services, such as the activation of the swap space, the EVMS volume manager, and more. The boot script, which is activated with the following line in /etc/inittab, starts all these services:
The main function of the boot script is to start a bunch of services. These services have their own start scripts in the directory /etc/init.d. The name of this script starts with boot, followed by the name of the service. For example, the boot.evms script starts on a server where EVMS is needed. To make sure the right scripts start upon system initialization, you need to activate them somehow. You can do this manually or with YaST.
