The runlevels field is # completely ignored by BusyBox init. If you want runlevels, use sysvinit. # # # Format for each entry: <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, it is completely ignored. Also note that if # BusyBox detects that a serial console is in use, then all entries # containing non-empty id fields will _not_ 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, # restart, ctrlaltdel, and shutdown. # # Note: askfirst acts just like respawn, but 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. # # Note: unrecognised actions (like initdefault) will cause init to emit # an error message, and then go along with its business. # # <process>: Specifies the process to be executed and it's command line. # # Note: 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 # ::ctrlaltdel:/sbin/reboot # ::shutdown:/sbin/swapoff -a # ::shutdown:/bin/umount -a -r # ::restart:/sbin/init # # if it detects that /dev/console is _not_ a serial console, it will # also run: # tty2::askfirst:/bin/sh # tty3::askfirst:/bin/sh # tty4::askfirst:/bin/sh # # Boot-time system configuration/initialization script. # This is run first except when booting in single-user mode. # ::sysinit:/etc/init.d/rcs 76
