Linux 2.6 - man page for init (linux section 8)

init(8) 										  init(8)

NAME
       init - Upstart process management daemon

SYNOPSIS
       init [OPTION]...

DESCRIPTION
       init  is  the  parent  of all processes on the system, it is executed by the kernel and is
       responsible for starting all other processes; it is the parent of all processes whose nat-
       ural parents have died and it is responsible for reaping those when they die.

       Processes  managed  by  init  are  known as jobs and are defined by files in the /etc/init
       directory.  See init(5) for more details on configuring Upstart.

   Events
       init(8) is an event-based init daemon.  This means that jobs will be automatically started
       and  stopped  by  changes  that	occur  to the system state, including as a result of jobs
       starting and stopping.

       This is different to dependency-based init daemons which start a  specified  set  of  goal
       jobs,  and  resolve  the  order in which they should be started and other jobs required by
       iterating their dependencies.

       For more information on starting and stopping jobs, as well as emitting events  that  will
       automatically start and stop jobs, see the manual page for the initctl(8) tool.

       The  primary  event  is the startup(7) event, emitted when the daemon has finished loading
       its configuration.  Other useful events are the starting(7), started(7),  stopping(7)  and
       stopped(7) events emitted as jobs change state.

       See upstart-events(7) for a summary of well-known events.

   System V compatibility
       The  Upstart  init(8)  daemon  does  not  keep track of runlevels itself, instead they are
       implemented entirely by its userspace tools.  The event emitted to  signify  a  change  of
       runlevel is the runlevel(7) event.  For more information see its manual page.

OPTIONS
       Options are passed to init(8) by placing them on the kernel command-line.

       --confdir directory
	      Read job configuration files from a directory other than /etc/init.

       --no-sessions
	      Disable user and chroot sessions.

       --no-startup-event
	      Suppress emission of the initial startup event. This option should only be used for
	      testing since it will stop the init(8) daemon from starting any jobs automatically.

       --session
	      Connect to the D-Bus session bus. This should only be used for testing.

       --startup-event event
	      Specify a different initial startup event from the standard startup(7).

       --verbose
	      Outputs verbose messages about job state changes and event emissions to the  system
	      console or log, useful for debugging boot.

NOTES
       init  is  not  normally executed by a user process, and expects to have a process id of 1.
       If this is not the case, it will actually execute telinit(8) and  pass  all  arguments  to
       that.  See that manual page for further details.

FILES
