NAME
       init, telinit - process control initialization

DESCRIPTION
   Init
       Init is the parent of all processes.  Its primary role is to
       create processes from a script stored in the file
       /etc/inittab (see inittab(5)).  This file usually has entries
       which cause init to spawn gettys on each line that users
       can log in.  It also controls autonomous processes
       required by any particular system.

RUNLEVELS
       A  runlevel  is  a software configuration of the system
       which allows only a selected group of processes to exist.
       The processes spawned by init for each of these runlevels
       are defined in the /etc/inittab file.  Init can be in one of
       eight  runlevels:  0–6  and  S  (a.k.a. s).  The runlevel
       is changed by having a privileged user run telinit, which
       sends appropriate signals to init, telling it which runlevel
       to change to.

       Runlevels S, 0, 1, and 6 are reserved.  Runlevel S is used
       to initialize the system on boot.  When starting runlevel S
       (on boot) or runlevel 1 (switching from a multi-user
       runlevel) the system is entering ``single-user mode'',
       after which the current runlevel is S.  Runlevel 0 is used
       to halt the system; runlevel 6 is used to reboot the system.

       After booting through S the system automatically enters
       one of the multi-user runlevels 2 through 5, unless there
       was some problem that needs to be fixed by the
       administrator in single-user mode.  Normally after entering
       single-user mode the administrator performs maintenance
       and then reboots the system.

BOOTING
       After init is invoked as the last step of the kernel boot
       sequence, it looks for the file /etc/inittab to see if there
       is an entry of the type initdefault (see inittab(5)). The
       initdefault entry determines the initial runlevel of the
       system.  If there is no such entry (or no /etc/inittab at
       all), a runlevel must be entered at the system console.

       Runlevel S or s initialize the system and do not require
       an /etc/inittab file.

       In single user mode, /sbin/sulogin is invoked on
       /dev/console.

       When entering single user mode, init initializes the
       consoles stty settings to sane values. Clocal mode is set.
       Hardware speed and handshaking are not changed.

       When entering a multi-user mode for the first time, init
       performs the boot and bootwait entries to allow file
       systems to be mounted before users can log in.  Then all
       entries matching the runlevel are processed.

       When starting a new process, init first checks whether the
       file /etc/initscript exists. If it does, it uses this script  to
       start the process.

       Each time a child terminates, init records the fact and the
       reason it died in /var/run/utmp and /var/log/wtmp, provided
       that these files exist.

BOOTFLAGS
       It  is  possible  to  pass  a  number of flags to init from the
       boot monitor (GRUB). Init accepts the following flags:

       -s, S, single
            Single user mode boot. In this mode /etc/inittab is
            examined and the bootup rc scripts are usually run before
            the single user mode shell is started.

       1-5  Runlevel to boot into.
