this is not retorical, because there is difference. On alioth I can do many
commits and push "when it's ready" and when it can be build. This makes git
history much cleaner. It needs to be buildable after push, not after
commit. Now I need to make all changes in one commit. Git history is
completely useless/unreadable now.
BTW: Same flow are used in github+travis. Merge request (which can be more
than one commit) needs to be buildable, not all single commits.

14-18 November. Enable, disable, enable some of them, ...
If I remember correctly I wanted newer pycodestyle and libgit2.
There's 2 options for us to use: --download-from-jessie-backports (which

I mean something different. I would use jessie-backports official backports
(in /etc/apt/sources.list) during our build and only if package is not in
official j-bpo repo, add them to auto-backports. And only for short time,
because we should upload them to j-bpo.
So simple flow:
* build our packages using official j + j-bpo repos
* when i need newer/completly new b-d which is not in j-bpo, add it to
* upload it to j-bpo
* remove from auto-backports
So keep auto-backports as small as possible. Example: Why we should build
debhelper for j-bpo ourself if there is working+tested version in j-bpo
already? We are uploading final packages to j-bpo repo, so it MUST work
with other j-bpo packages. And if we don't want wait for dak/other
maintainers, use auto-backports.
