@ Capricorny

I would like to encourage you to take Klaus up on his offer in his post #29
to present him with 'the automation' to make 'poor-man's re-mastering'
a menu item in some later Knoppix release.

One way to do this might be first to lay out a proof of principle that others
on this forum might emulate and/or suggest improvements to. You've probably
done this already, and only need to collect all your notes, and Forester's
as well if they are relevant, in one place.

It may be more likely to succeed earlier, as a Knoppix refinement, if squashfs
vs cloop differences were left to be suggested as a subsequent refinement
of the basic idea.

I know you also have an avenue to address this on the debian-knoppix mailing list.
I wish you good luck in this however you choose to proceed.
