Can either of these be fed back to bring a system's package state back to what it was originally? This is the purpose of --get-selections (with the corresponding --set-selections). Also, what happens if a user doesn't use aptitude at all, and uses apt-get instead? Will there be any useful restore information using these aptitude methods? micah
