I have a filesystem loop mounted on /mnt/arm/2, and the following 
scripts makes a new filesystem (dd if=/dev/zero and mke2fs), copies the 
files, and gzips the new filesystem. This is done mainly to make sure 
all unused blocked in the filesystem are zeros, so as to have minimum 
gzipped size.


#!/bin/sh
IMAGE=/home/matan/arm/images/1
umount /mnt/arm/1
dd if=/dev/zero of=$IMAGE bs=1048576 count=4
mke2fs -F -m 0 $IMAGE
mount /mnt/arm/1
cp -a /mnt/arm/2/* /mnt/arm/1
umount /mnt/arm/1
chown matan.users $IMAGE
gzip -c -9 $IMAGE > /usr/src/arm/jornada820/b2/ramdisk/ramdiskimage.gz
chown matan.users /usr/src/arm/jornada820/b2/ramdisk/ramdiskimage.gz
