10
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
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
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.
