best advice i can give:
keep the old drive that has debian on around for a while and install
on a new drive, that way everything is available easily.
second best advise i can give:
back up the entire drive
third best i can give:
what you have there covers most of it, check to see you don't have
anything in /usr/local, there are other scattered directories that
sometimes have things, e.g. i put some cgi scripts in /usr/lib/cgi-bin,
I have tons of stuff in /usr/local and /usr/src, backup the kernel
in /boot if you rolled your own kernel ..
it would be cool if there was(maybe there is?) a utility that could
scan every file on the system and identify those which are not
part of a package, would make for easy backups! or even better compare
the md5sums of the ones against the packages, and mark those as well
to backup changed files.(though I seem to remember reading that not
all packages come with md5sums on the installed files)
