1 # /etc/inittab init(8) configuration for BusyBox

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, it is completely ignored. Also note that if
19 # BusyBox detects that a serial console is in use, then all entries
20 # containing non-empty id fields will _not_ be run. BusyBox init does
21 # nothing with utmp. We don't need no stinkin' utmp.
23 # <runlevels>: The runlevels field is completely ignored.
25 # <action>: Valid actions include: sysinit, respawn, askfirst, wait, once,
26 # restart, ctrlaltdel, and shutdown.
28 # Note: askfirst acts just like respawn, but before running the specified
29 # process it displays the line "Please press Enter to activate this
30 # console." and then waits for the user to press enter before starting
31 # the specified process.
33 # Note: unrecognised actions (like initdefault) will cause init to emit
34 # an error message, and then go along with its business.
36 # <process>: Specifies the process to be executed and it's command line.
38 # Note: BusyBox init works just fine without an inittab. If no inittab is
39 # found, it has the following default behavior:
40 # ::sysinit:/etc/init.d/rcS
42 # ::ctrlaltdel:/sbin/reboot
43 # ::shutdown:/sbin/swapoff -a
44 # ::shutdown:/bin/umount -a -r
45 # ::restart:/sbin/init
47 # if it detects that /dev/console is _not_ a serial console, it will
49 # tty2::askfirst:/bin/sh
50 # tty3::askfirst:/bin/sh
51 # tty4::askfirst:/bin/sh
53 # Boot-time system configuration/initialization script.
54 # This is run first except when booting in single-user mode.
56 ::sysinit:/etc/init.d/rcS
58 # /bin/sh invocations on selected ttys
60 # Note below that we prefix the shell commands with a "-" to indicate to the
61 # shell that it is supposed to be a login shell. Normally this is handled by
62 # login, but since we are bypassing login in this case, BusyBox lets you do
65 # Start an "askfirst" shell on the console (whatever that may be)
67 # Start an "askfirst" shell on /dev/tty2-4
68 tty2::askfirst:-/bin/sh
69 tty3::askfirst:-/bin/sh
70 tty4::askfirst:-/bin/sh
72 # /sbin/getty invocations for selected ttys
73 tty4::respawn:/sbin/getty 38400 tty5
74 tty5::respawn:/sbin/getty 38400 tty6
76 # Example of how to put a getty on a serial line (for a terminal)
77 #::respawn:/sbin/getty -L ttyS0 9600 vt100
78 #::respawn:/sbin/getty -L ttyS1 9600 vt100
80 # Example how to put a getty on a modem line.
81 #::respawn:/sbin/getty 57600 ttyS2
83 # Stuff to do when restarting the init process
86 # Stuff to do before rebooting
