I am set forth on an adventure to recompile Clonezilla to add a proprietary driver. In any case, following the instructions here: unsquashfs ala Clonezilla

In step 4, sudo unsquashfs filesystem.squashfs, fails miserably with:

root@debian:~/squashfs-tmp# unsquashfs filesystem.squashfs
Parallel unsquashfs: Using 2 processors
zlib::uncompress failed, unknown error -3
read_block: failed to read block @0x58b68e4
read_fragment_table: failed to read fragment table index
FATAL ERROR aborting: failed to read fragment table

Based on some googling I suspect you have a mismatch between the version of squashfs used to create the filesystem and the version you are trying to use to uncompress it. What version of squashfs do you have installed? I recommend you try upgrading to a newer version and see if that helps.

I will install the same version of debian on my domU, and will build everything based upon what the CloneZilla team used :) – CMag Sep 15 '11 at 21:12
If you want to see a crazy mind puzzle, i made a video of how my genisofs is breaking, and how much hair i had to pull out, until i made a youtube video for any help possible :) – CMag Sep 15 '11 at 21:13 – CMag Sep 15 '11 at 21:13
