Another follow-up: I liked the edits so much that I did some more editing. Now, my default will load home and configuration from my hard drive, as above. I also created a cheat code "hd" that will not only load my home and configuration, it will load Knoppix from my Poor Man's Install. So all I have to do is type "hd".

I can lend the CD-ROM to someone who doesn't already have Knoppix and would like to try it. With no codes entered, it looks for the non-existent home and configuration, but does not crash.
