Usage:
    init 


Usage:
    init 

Init is the first process started during boot. It never exits.








This version of init is designed to be run only by the kernel.

BusyBox init doesn't support multiple runlevels. The runlevels field of
the /etc/inittab file is completely ignored by BusyBox init. If you want
runlevels, use sysvinit.

BusyBox init works just fine without an inittab. If no inittab is found,
it has the following default behavior:

        ::sysinit:/etc/init.d/rcS
        ::askfirst:/bin/sh
        ::ctrlaltdel:/sbin/reboot
        ::shutdown:/sbin/swapoff -a
        ::shutdown:/bin/umount -a -r
        ::restart:/sbin/init
        tty2::askfirst:/bin/sh
        tty3::askfirst:/bin/sh
        tty4::askfirst:/bin/sh

If you choose to use an /etc/inittab file, the inittab entry format is as follows:

        <id>:<runlevels>:<action>:<process>

        <id>:

                WARNING: This field has a non-traditional meaning for BusyBox init!
                The id field is used by BusyBox init to specify the controlling tty for
                the specified process to run on. The contents of this field are
                appended to                 be unique, although if it isn't you may have strange results. If this
                field is left blank, then the init's stdin/out will be used.

        <runlevels>:

                The runlevels field is completely ignored.

        <action>:

                Valid actions include: sysinit, respawn, askfirst, wait,
                once, restart, ctrlaltdel, and shutdown.

                The available actions can be classified into two groups: actions
                that are run only once, and actions that are re-run when the specified
                process exits.

                Run only-once actions:

                        'sysinit' is the first item run on boot. init waits until all
                        sysinit actions are completed before continuing. Following the
                        completion of all sysinit actions, all 'wait' actions are run.
                        'wait' actions, like 'sysinit' actions, cause init to wait until
                        the specified task completes. 'once' actions are asynchronous,
                        therefore, init does not wait for them to complete. 'restart' is
                        the action taken to restart the init process. By default this should
                        simply run /sbin/init, but can be a script which runs pivot_root or it
                        can do all sorts of other interesting things. The 'ctrlaltdel' init
                        actions are run when the system detects that someone on the system
                        console has pressed the CTRL-ALT-DEL key combination. Typically one
                        wants to run 'reboot' at this point to cause the system to reboot.
                        Finally the 'shutdown' action specifies the actions to taken when
                        init is told to reboot. Unmounting filesystems and disabling swap
                        is a very good here.

                Run repeatedly actions:

                        'respawn' actions are run after the 'once' actions. When a process
                        started with a 'respawn' action exits, init automatically restarts
                        it. Unlike sysvinit, BusyBox init does not stop processes from
                        respawning out of control. The 'askfirst' actions acts just like
                        respawn, except that before running the specified process it
                        displays the line                         and then waits for the user to press enter before starting the
                        specified process.

                Unrecognized actions (like initdefault) will cause init to emit an
                error message, and then go along with its business. All actions are
                run in the order they appear in /etc/inittab.

        <process>:

                Specifies the process to be executed and its command line.

Example /etc/inittab file:

        # This is run first except when booting in single-user mode
        #
        ::sysinit:/etc/init.d/rcS
        
        # /bin/sh invocations on selected ttys
        #
        # Start an         ::askfirst:-/bin/sh
        # Start an         tty2::askfirst:-/bin/sh
        tty3::askfirst:-/bin/sh
        tty4::askfirst:-/bin/sh
        
        # /sbin/getty invocations for selected ttys
        #
        tty4::respawn:/sbin/getty 38400 tty4
        tty5::respawn:/sbin/getty 38400 tty5
        
        
        # Example of how to put a getty on a serial line (for a terminal)
        #
        #::respawn:/sbin/getty -L ttyS0 9600 vt100
        #::respawn:/sbin/getty -L ttyS1 9600 vt100
        #
        # Example how to put a getty on a modem line
        #::respawn:/sbin/getty 57600 ttyS2
        
        # Stuff to do when restarting the init process
        ::restart:/sbin/init
        
        # Stuff to do before rebooting
        ::ctrlaltdel:/sbin/reboot
        ::shutdown:/bin/umount -a -r
        ::shutdown:/sbin/swapoff -a
