1# /etc/inittab init(8) configuration for BusyBox 2# 3# Copyright (C) 1999 by Lineo, inc. Written by Erik Andersen 4# <andersen@lineo.com>, <andersee@debian.org> 5# 6# 7# Note, BusyBox init doesn't support runlevels. The runlevels field is 8# completely ignored by BusyBox init. If you want runlevels, use sysvinit. 9# 10# 11# Format for each entry: <id>:<runlevels>:<action>:<process> 12# 13# <id>: WARNING: This field has a non-traditional meaning for BusyBox init! 14# 15# The id field is used by BusyBox init to specify the controlling tty for 16# the specified process to run on. The contents of this field are 17# appended to "/dev/" and used as-is. There is no need for this field to 18# be unique, although if it isn't you may have strange results. If this 19# field is left blank, it is completely ignored. Also note that if 20# BusyBox detects that a serial console is in use, then all entries 21# containing non-empty id fields will _not_ be run. BusyBox init does 22# nothing with utmp. We don't need no stinkin' utmp. 23# 24# <runlevels>: The runlevels field is completely ignored. 25# 26# <action>: Valid actions include: sysinit, respawn, askfirst, wait, once, 27# ctrlaltdel, and shutdown. 28# 29# Note: askfirst acts just like respawn, but before running the specified 30# process it displays the line "Please press Enter to activate this 31# console." and then waits for the user to press enter before starting 32# the specified process. 33# 34# Note: unrecognised actions (like initdefault) will cause init to emit 35# an error message, and then go along with its business. 36# 37# <process>: Specifies the process to be executed and it's command line. 38# 39# Note: BusyBox init works just fine without an inittab. If no inittab is 40# found, it has the following default behavior: 41# ::sysinit:/etc/init.d/rcS 42# ::askfirst:/bin/sh 43# ::ctrlaltdel:/sbin/reboot 44# ::shutdown:/sbin/swapoff -a 45# ::shutdown:/bin/umount -a -r 46# if it detects that /dev/console is _not_ a serial console, it will 47# also run: 48# tty2::askfirst:/bin/sh 49# tty3::askfirst:/bin/sh 50# tty4::askfirst:/bin/sh 51# 52# Boot-time system configuration/initialization script. 53# This is run first except when booting in single-user mode. 54# 55::sysinit:/etc/init.d/rcS 56 57# /bin/sh invocations on selected ttys 58# 59# Note below that we prefix the shell commands with a "-" to indicate to the 60# shell that it is supposed to be a login shell.
