Backup /etc & you home dir
Yeah, that's always a solution. My home dir is quite large, but I guess I could sort out the important stuff quite easily.
Anyway, I might as well ask another thing. The reason I was thinking of changing to Debian is that the mirrors for Mandrake's urpmi tool always seem to contain really old versions of programs, and I get the feeling that Debian's apt-get is much better if you want the latest versions of all programs. Is that true?
