hi,
	i've done it. Basically what u need to do is shutdown all
processes, send all processes the TERM & KILL ( through /sbin/killall5),
and then unmount the file systems ( especially /proc) and then start
/etc/rc.sysinit.


	 i wrote my own init level 7, from where i start all the shutdown 
scripts of /etc/rc.d/rc5.d ( K??*) 
First of all 
.......create a directory /etc/rc.d/rc7.d ( /sbin/init.d/ in suse)
.......edit /etc/inittab, and add an unused runlevel specification , say
7.
.......link all the files in /etc/rc.d/init.d with the /etc/rc.d/rc7.d
with the names starting from K{num}
.......the last number say K90+ should be a script that starts up
/etc/rc.sysinit and switches to a default runlevel, with
	cat /etc/inittab | egrep ^initdefault|awk -F: '{print $2}'
....... and then call init 7 / telinit 7

hope this helps
