Comment 1 for bug 899972

As a matter of interest (although it would be a separate bug, and is lower priority), a good item of future work would be to move the process of generating extra overrides to before apt-ftparchive runs, and have it read the state of the archive from the Launchpad database rather than from the published archive on disk. This would fix the extremely long-standing problem that germinate output is itself an input to the archive state, and so there are some changes that require multiple publisher runs to publish completely.

I've tried to design python-germinate's archive interface so that this should be possible, although I haven't yet actually used it this way in practice.
