Right...  One could ALMOST base this on whether the RPM Database has
been modified (although one would need a flag for whether an
RPM-installed file has been modified, but that's relatively rare).

Right..

The problem is that sometimes I _do_ modify rpm-installed binaries
(for one reason or another).  So I don't want to just out-right
exclude /bin, /sbin, /usr, or /lib.

As for backing up all of /etc -- I don't want to do that..  For
example, there is no reason to backup /etc/services, and if I
re-install I probably want to newly-installed /etc/services instead of
my backed-up version!
