In other word: Never useable by APT or a(ny other) sane front-end. Beside that i wonder which --force flag this should be, given that it removes packages while it was requested to install others. In a way, the old architecture is disappearing, but there are no Replaces (not even implicit) in place to allow that and the implicit Conflicts wouldn't allow a seamless disappearing anyway. So implementing this sounds for me a bit like black voodoo… Best regards David Kalnischkies -- To UNSUBSCRIBE, email to debian-dpkg-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
