1 # /etc/inittab init(8) configuration for BusyBox
3 # Copyright (C) 1999-2004 by Erik Andersen <andersen@codepoet.org>
6 # Note, BusyBox init doesn't support runlevels. The runlevels field is
7 # completely ignored by BusyBox init. If you want runlevels, use sysvinit.
10 # Format for each entry: <id>:<runlevels>:<action>:<process>
12 # <id>: WARNING: This field has a non-traditional meaning for BusyBox init!
14 # The id field is used by BusyBox init to specify the controlling tty for
15 # the specified process to run on. The contents of this field are
16 # appended to "/dev/" and used as-is. There is no need for this field to
17 # be unique, although if it isn't you may have strange results. If this
18 # field is left blank, then the init's stdin/out will be used.
20 # <runlevels>: The runlevels field is completely ignored.
22 # <action>: Valid actions include: sysinit, respawn, askfirst, wait, once,
23 # restart, ctrlaltdel, and shutdown.
25 # Note: askfirst acts just like respawn, but before running the specified
26 # process it displays the line "Please press Enter to activate this
27 # console." and then waits for the user to press enter before starting
28 # the specified process.
30 # Note: unrecognized actions (like initdefault) will cause init to emit
31 # an error message, and then go along with its business.
33 # <process>: Specifies the process to be executed and it's command line.
35 # Note: BusyBox init works just fine without an inittab. If no inittab is
36 # found, it has the following default behavior:
37 # ::sysinit:/etc/init.d/rcS
39 # ::ctrlaltdel:/sbin/reboot
40 # ::shutdown:/sbin/swapoff -a
41 # ::shutdown:/bin/umount -a -r
42 # ::restart:/sbin/init
43 # tty2::askfirst:/bin/sh
44 # tty3::askfirst:/bin/sh
45 # tty4::askfirst:/bin/sh
47 # Boot-time system configuration/initialization script.
48 # This is run first except when booting in single-user mode.
50 ::sysinit:/etc/init.d/rcS
52 # /bin/sh invocations on selected ttys
54 # Note below that we prefix the shell commands with a "-" to indicate to the
55 # shell that it is supposed to be a login shell. Normally this is handled by
56 # login, but since we are bypassing login in this case, BusyBox lets you do
59 # Start an "askfirst" shell on the console (whatever that may be)
61 # Start an "askfirst" shell on /dev/tty2-4
62 tty2::askfirst:-/bin/sh
63 tty3::askfirst:-/bin/sh
64 tty4::askfirst:-/bin/sh
66 # /sbin/getty invocations for selected ttys
67 tty4::respawn:/sbin/getty 38400 tty5
68 tty5::respawn:/sbin/getty 38400 tty6
70 # Example of how to put a getty on a serial line (for a terminal)
71 #::respawn:/sbin/getty -L ttyS0 9600 vt100
72 #::respawn:/sbin/getty -L ttyS1 9600 vt100
74 # Example how to put a getty on a modem line.
75 #::respawn:/sbin/getty 57600 ttyS2
77 # Stuff to do when restarting the init process
80 # Stuff to do before rebooting
81 ::ctrlaltdel:/sbin/reboot
82 ::shutdown:/bin/umount -a -r
83 ::shutdown:/sbin/swapoff -a
