Oh you don't use grml-live at all, I should have read your posting
more carefully. ;)

So it might be that you have to use the "-nolzma" option in the
mksquashfs command line when building it manually. My previous
comments keep valid though. :)

Does this fix your problem?

BTW: I suggest to take a look at grml-live [see
http://grml.org/grml-live/ for more details]. :)
