And then dpkg lists a few packages from Morphix were specifically modified for Ubuntu.
I don't think anyone ever tried to hide this. After all, all this information is pretty much in the open, from dmesg to the filesystem on the LiveCD. But it is interesting to see that it isn't mentioned anywhere, either. Not even by the Morphix's author.
So, here we go: Ubuntu 4.10 LiveCD is a Knoppix+debian derivative.
As far as I can tell, things have changed a lot in 5.04, so maybe this applies only to Ubuntu 4.10.
