In that case the only sane thing to do is assume that every file on the box
changed and rebuild it from scratch from the backups. Upgrading will touch
nearly everything in /etc, /dev, /sbin/, /usr/bin/, /usr/sbin, /usr/lib,
/modules, /usr/include, and so forth. It won't (or shouldn't...) touch
antyhing in /usr/local, /home or in any filesystem not mentioned in hier(7).
