Thanks.

Prolly a good idea.

I wasn't aware of the issues of overwriting files with ext3 until
recently. OTOH, I may later dispose of this machine, and I wouldn't
want their information falling into other people's hands. I don't
want to have to remember to do something extreme a few years later.
I'd like to just wipe the files, and be done with it. Overwriting
swap is probably a good idea, and likely easy to do. Hmm. Maybe not.
Does the Fedora rescue CD automatically mount a swap partition if
it finds it? Knoppix does. Maybe there is a way to tell Knoppix
not to. I'll have to investigate that.

Thanks for the reply.

I can explain it for you, but I can't understand it for you.
I speak only for myself, and I am unanimous in that!
