The - runlevels field of the /etc/inittab file is completely - ignored by BusyBox init. If you want runlevels, use - sysvinit. - - - - BusyBox init works just fine without an inittab. If no - inittab is found, it has the following default behavior: - - - - - ::sysinit:/etc/init.d/rcS - ::askfirst:/bin/sh - - - - - If it detects that /dev/console is _not_ a serial - console, it will also run: - - - - - tty2::askfirst:/bin/sh - - - - - If you choose to use an /etc/inittab file, the inittab - entry format is as follows: - - - - - <id>:<runlevels>:<action>:<process> - - - - - id - - - WARNING: This field has a non-traditional meaning for BusyBox init! - The id field is used by BusyBox init to specify the controlling tty - for the specified process to run on. The contents of this field - are appended to "/dev/" and used as-is. There is no need for this - field to be unique, although if it isn't you may have strange - results. If this field is left blank, the controlling tty is set - to the console. Also note that if BusyBox detects that a serial - console is in use, then only entries whose controlling tty is - either the serial console or /dev/null will be run. BusyBox init - does nothing with utmp. We don't need no stinkin' utmp. - - - - - - runlevels - - - The runlevels field is completely ignored. - - - - - action - - - - Valid actions include: sysinit, respawn, askfirst, wait, - once, and ctrlaltdel. - - - - - The available actions can be classified into two groups: actions - that are run only once, and actions that are re-run when the specified - process exits. - - - - Run only-once actions: - - - - 'sysinit' is the first item run on boot. init waits until all - sysinit actions are completed before continuing. Following the - completion of all sysinit actions, all 'wait' actions are run. - 'wait' actions, like 'sysinit' actions, cause init to wait until - the specified task completes. 'once' actions are asyncronous, - therefore, init does not wait for them to complete. 'ctrlaltdel' - actions are run immediately before init causes the system to reboot - (unmounting filesystems with a 'ctrlaltdel' action is a very good - idea). - - - - Run repeatedly actions: - - - - 'respawn' actions are run after the 'once' actions. When a process - started with a 'respawn' action exits, init automatically restarts - it. Unlike sysvinit, BusyBox init does not stop processes from - respawning out of control. The 'askfirst' actions acts just like - respawn, except that before running the specified process it - displays the line "Please press Enter to activate this console." - and then waits for the user to press enter before starting the - specified process. - - - - Unrecognized actions (like initdefault) will cause init to emit an - error message, and then go along with its business. All actions are - run in the reverse order from how they appear in /etc/inittab. - - - - - - process - - - Specifies the process to be executed and its - command line. - - - - - Example /etc/inittab file - - - - # This is run first except when booting in single-user mode. - # - ::sysinit:/etc/init.d/rcS - - # /bin/sh invocations on selected ttys - # - # Start an "askfirst" shell on the console (whatever that may be) - ::askfirst:-/bin/sh - # Start an "askfirst" shell on /dev/tty2-4 - tty2::askfirst:-/bin/sh - tty2::askfirst:-/bin/sh - tty2::askfirst:-/bin/sh - - # /sbin/getty invocations for selected ttys - # - tty4::respawn:/sbin/getty 38400 tty5 - tty5::respawn:/sbin/getty 38400 tty6 - - # Example of how to put a getty on a serial line (for a terminal) - # - #::respawn:/sbin/getty -L ttyS0 9600 vt100 - #::respawn:/sbin/getty -L ttyS1 9600 vt100 - # - # Example how to put a getty on a modem line. - #::respawn:/sbin/getty 57600 ttyS2 - - # Stuff to do before rebooting - ::ctrlaltdel:/bin/umount -a -r - ::ctrlaltdel:/sbin/swapoff - - - - - - - insmod - - - Usage: insmod [OPTION]...

BusyBox has made it Policy that it will never use - NSS, and will never use libc calls that make use of NSS. This - allows you to run an embedded system without the need for - installing an /etc/nsswitch.conf file and without /lib/libnss_* - libraries installed. - - - - If you are using a system that is using a remote LDAP server for - authentication via GNU libc NSS, and you want to use BusyBox, - then you will need to adjust the BusyBox source. Chances are - though, that if you have enough space to install of that stuff - on your system, then you probably want the full GNU utilities. - - - - - SEE ALSO - - - textutils(1), - shellutils(1), - etc... - - - - - MAINTAINER - - - Erik Andersen <andersen@codepoet.org> - - - - - AUTHORS - - - The following people have made significant contributions to - BusyBox -- whether they know it or not. - - - - Erik Andersen <andersen@codepoet.org> - - - - Edward Betts <edward@debian.org> - - - - John Beppu <beppu@codepoet.org> - - - - Brian Candler <B.Candler@pobox.com> - - - - Randolph Chung <tausq@debian.org> - - - - Dave Cinege <dcinege@psychosis.com> - - - - Karl M.
