Greetings again, John.

Re-reading your initial post, it occurs to me that perhaps you just didn't find the right
directory for your earlier attempts. The following is an earlier post of mine where
I used Klaus K's update*.tar.gz idea. It looks like /mnt-system is what Klaus means
by "on the medium holding the KNOPPIX data". Give that a try. It worked for me.
