    Hello SuSE folkz,
    I have some questions regarding properties of SysV init daemon.
    It starts on a system boot up by the kernel call to /sbin/init.
    Then init reads /etc/inittab and starts/stops services in /etc/inint.d
    After system has booted into default run level (e.g 5) init still
    continues to run as a daemon.
    Does it have any other purposes other than idling in the loop with
    uid 1 and gid 0?
    Isn't it right that kernel itself takes care about parent processes
    and its children?
    Why do we need init running as a daemon after a system is running in
    default runlevel?
    I can start and stop any service without init involved.
    Could somebody please give me a pointer to the source of information
    regarding all properties of init.

    Thanks in advance,

    Alex
