We migrated from bzr to git just yet. Michael didn't throw a big party, but he announced it to the relevant peers (aka on [email protected]).

Yeap, we don't have a verbose flag – we have a bunch of debug options instead as activating all of them would produce a LOT of noise. The problem here though is less a debug problem as this can be recreated "easily" by having a multi-arch enabled system, an i386- and an amd64-only CD-ROM configured and an upgrade for a M-A:same library you have installed for i386 and amd64. The problem is that if APT needs to upgrade a library it has to tell dpkg to unpack the i386.deb and the amd64.deb at the same time, so for that to work it needs access to both files which it doesn't have if you switch CD-ROMs (aka: you need a second drive, usb sticks might work, too). To make it work with one drive, APT would need to copy the amd64.deb package to disk, ask you to switch, and whola, it has both files. Only problem: You would be going to switch a lot as you basically have to switch for each library you have installed both architectures (and sometimes back). So, to prevent people from going insane over switching a thousand times APT would need to copy all those library files at once – or at least as many as possible without eating all harddrive space. The first should be easy, the second step a bit harder, but both will not be fixed by me as I never used APT with CD-ROMs (nor do I use CD-ROMs at all if I think about it now…). That needs someone with more CD-ROM experience to pick it up as this really needs someone who can actually test what she/he is doing. I am happy to help with pointers/answers/reviews/… on the other hand, hence tagged as 'gift' [0].
