=item halt
+Usage: halt

=item hostid
+Usage: hostid
+
+Prints out a unique 32-bit identifier for the current

+among all UNIX systems in existence.
-------------------------------
=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
+ tty2::askfirst:/bin/sh
+
+ # /sbin/getty invocations for selected ttys
+ #
+ tty4::respawn:/sbin/getty 38400 tty4
+ tty5::respawn:/sbin/getty 38400 tty5
+
+
+ # Example of how to put a getty on a serial line (for a terminal)
+ #
+ #ttyS0::respawn:/sbin/getty -L ttyS0 9600 vt100
+ #ttyS1::respawn:/sbin/getty -L ttyS1 9600 vt100
+ #
+ # Example how to put a getty on a modem line.
+ #ttyS2::respawn:/sbin/getty -x0 -s 57600 ttyS2
+
+ # Stuff to do before rebooting
+ ::ctrlaltdel:/bin/umount -a -r > /dev/null 2>&1
+ ::ctrlaltdel:/sbin/swapoff -a > /dev/null 2>&1
