=item init
|
||||
|
||||
Usage: init
|
||||
|
||||
Init is the parent of all processes.
|
||||
|
||||
This version of init is designed to be run only by the kernel.
|
||||
|
||||
BusyBox init doesn't support multiple runlevels. 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, 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, and ctrlaltdel.
|
||||
|
||||
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.
|
||||
|
||||
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.
|
||||
|
||||
|
||||
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
