Good idea - I added such a column

Right now I'm looking at parted magic - I want to add a script to mount a nfs and run a script there 
- but I'm having problems extracting the squashfs on my Debian box..

# unsquashfs fmu.sqfs
Parallel unsquashfs: Using 4 processors
zlib::uncompress failed, unknown error -3
read_block: failed to read block @0x1a70a41
read_fragment_table: failed to read fragment table index
FATAL ERROR aborting: failed to read fragment tabl

??
/proc/filesystems lists squashfs

I can't mount these - they don't seem to be otherwise compressed??

# file fmu.sqfs
fmu.sqfs: Squashfs filesystem, little endian, version 4.0

# squashfs-tools   1:4.0-8

# mount -o loop -t  squashfs fmu.sqfs mnt
mount: wrong fs type, bad option, bad superblock on /dev/loop0,
        missing codepage or helper program, or other error


I've not worked with squashfs before - what am I missing?.. Google isn't getting me there.

Interesting page - seems they left out jfs and ext4 for smart copying..

My main effort was to find something that would pxe boot - or run completely out of RAM. (I'm 
actually booting  off a SSD drive for speed, but want to be able to unplug the boot drive for access 
to the SATA ports. )
