The problem is not the diffing, but getting the proper list... But you're right, it might work with libapt-pkg-perl. Maybe it also works with something as simple as feeding the list of explicit packages into apt-get install with the no-action option?!

Removing classes, too. It's not as much a bad idea as Thomas said, that's why I wrote I disagree with him. The next step would be to track changes made by classes, to reverse-patch changed files, to get some sort of "undo" function, to really remove changes made by classes. I had a presentation with a potential customer who asked for this - even more, for the ability to go back to a specific state - or at least one step back like "before the last softupdate" - even better "before the last three softwupdates" or "state of 2008-10-22"... interestintg things, but here we are really talking rather weeks than days of work. It would be cool to have these things - let's find somebody to implement it :) By the way, anwother interesting project that seems to deal with the difference between the ideal that one only has exactly configured system only changed by the config management system, versus the reality that somtimes fast manual changes are necessary(in an emergency, as well as in development of some configuration, you cannot always run the system for every little change) is this one: http://cft.et.redhat.com/ Henning - -- Henning Sprang http://www.sprang.de -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFJRBkyOzXGJHJLmQIRAsMJAKCEZY5d+iaDRPRl3mc6WJH5cT50vwCghbfW kKiXda2WW8+enYH3mPvmCeU= =/taB -----END PGP SIGNATURE-----
