Hi all,
I am manipulating a ram disk image.that is 7za compressed...
But i somehow am not able to get a hold of the command line for 7za compression and i need urgent help!!!
this is what am doing...

gzcat /path/to/directory/x86.microroot >/tmp/microroot
x=`lofiadm -a /tmp/microroot`
mount $x /mnt
cd /mnt
<edit what i want in the ramdisk,then>

cd /
umount /mnt
lofiadm -d /dev/lofi/1
7za a -tgzip -mx =9 /tmp/microroot /path/to/directory/x86.microroot
(if this is the other way round it wont work at all)...am new to this command line!!

i get the final acknowledgment as "everything is ok", after the compression..
but when i open up the ram disk again to see if my changes are reflected,its not???(the file is not write protected)

Is this command line wrong?

Please assist!!!
