[Grml] grml-halt on usb disk, for writing on unionfs

hi there

i have installed grml successfully on my cf card. i'm searching a way how to write my new configurations and files on the disk. i've found a way how to sync an unionfs with the originaly readonly mounted directory... but i'm a bit confused. i don't now how it should look like in the grml debian derivate.

here is the original debian wrap script:

#!/bin/bash # halt-wrap mount -o remount rw /OLD_ROOT/real_root rsync --delete -abRvz --exclude "/sys" --exclude "/proc" --exclude "/dev" --exclude "/OLD_ROOT" / /OLD_ROOT/real_root/ halt

should i copy this script in /usr/sbin or put it in /etc/init.d/ and modifier the /etc/rc.conf ( or something i don't remember anymore... because i'm using the symlinking stuff )??
