Yes, I was aware of Knoppix running inside a ramdisk which mounts the
cloop image. My question should have been more like: "does anybody have a
good idea how to actually *use* the now available read-only HD image?"

Thinking about it, maybe the easiest method would be to modify the initial
ramdisk so it does not mount the cloop device, but /dev/hda (note: this is
no partition, i.e. not /dev/hda1, but /dev/hda). That should work nicely.

In other news, I was been told that http://www.topologilinux.com/ has a
coLinux-System on the Live CD, so in order to demonstrate Linux, you could
include that...
