PPA (was: Bits from the Release Team - Kicking off Wheezy)

All that sounds very good to me.

Now, there are a few points that we could start tackling:

1. How to push from a vcs (git, svn, ...) to ppa? (This should be
coordinated with ftp-masters, so that the same method could be used
later on for uploading into unstable.)

2. How could we create new ppa repositories easy enough, how do we
hold the data, how do we make sure that dependencies are there?
(Basically "how do we extend dak for ppa?")

3. How do we extend authentication concepts for apt to ppa? (So that
one could say "please give me this and that repository from ppa", and
one doesn't need to add custom apt-keys.)

4. How do we get a good interface to see which patches are where, and
which bugs are found (or fixed) where?

5. After 2. is done, setting up autobuilding for ppa. (I'll be happy
to help with this part, but 2. needs to be done first.)

6. After 4. and 5. are done, adding links to the relevant build logs.

Any takers?
