NAME

6       init - Upstart process management daemon
7

SYNOPSIS

9       init [OPTION]...
10

DESCRIPTION

12       init  is  the  parent of all processes on the system, it is executed by
13       the kernel and is responsible for starting all other processes;  it  is
14       the  parent  of all processes whose natural parents have died and it is
15       responsible for reaping those when they die.
16
17       Processes managed by init are known as jobs and are defined by files in
18       the  /etc/init  directory.  See init(5) for more details on configuring
19       Upstart.
20
21   Events
22       init(8) is an event-based init daemon.  This means that  jobs  will  be
23       automatically  started  and stopped by changes that occur to the system
24       state, including as a result of jobs starting and stopping.
25
26       This is different to dependency-based init daemons which start a speci‐
27       fied  set  of  goal jobs, and resolve the order in which they should be
28       started and other jobs required by iterating their dependencies.
29
30       For more information on starting and stopping jobs, as well as emitting
31       events that will automatically start and stop jobs, see the manual page
32       for the initctl(8) tool.
33
34       The primary event is the startup(7) event, emitted when the daemon  has
35       finished loading its configuration.  Other useful events are the start‐
36       ing(7), started(7), stopping(7) and stopped(7) events emitted  as  jobs
37       change state.
38
39   System V compatibility
40       The  Upstart  init(8)  daemon  does not keep track of runlevels itself,
41       instead they are implemented entirely  by  its  userspace  tools.   The
42       event emitted to signify a change of runlevel is the runlevel(7) event.
43       For more information see its manual page.
44

OPTIONS

46       Options are passed to init(8) by placing them on  the  kernel  command-
47       line.
48
49       --verbose
50              Outputs verbose messages about job state changes and event emis‐
51              sions to the system console or log, useful for debugging boot.
52

NOTES

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