Hi guys, 
Clonezilla uses debian-for-live-ocs.iso as template to make restore-iso, I want remaster that debian iso and add my apps to it, but squashfs can't uncompress filesystem.squashfs file, it returns error. I have tested ubuntu-live-for-ocs too but It's same:

$unsquashfs filesystem.squashfs
Parallel unsquashfs: Using 4 processors
zlib::uncompress failed, unknown error -3
read_block: failed to read block @0x55c2aa6
read_fragment_table: failed to read fragment table index
FATAL ERROR aborting: failed to read fragment table

I checked the filesystem.squashfs of official ubuntu, it works well.

Where I can find the source of this debian image?(it's customized for clonezilla) where I can find the script that makes this image?
