Yes, I think the versioned provides is better, since making it harder to break the system is, I think, more important than easy downgrades. We could document the downgrade procedure in a NEWS.Debian entry, possibly. Unfortunately, none of this will help someone who installs only libkrb5-3 from the new packages and then removes it, I think. If so, I'm missing something. Hopefully, though, given that a new libkrb53 is available at the same time, very few people would ever do that. -- Russ Allbery (r...@debian.org) <http://www.eyrie.org/~eagle/> -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
