HOWTO rebuild the archive
I want to rebuild the whole archive on my box but I don't really know
where to start. I don't want to keep the resulting packages, I just want
to seek FTBFSes.
I've installed sbuild (do I really need it? Does pbuilder/cowbuilder
suffice?) and followed the instructions of the manpage to setup a build
environment. What would be the next step? How to I manage to get the
whole archive (testing) build? Is there a script or something?
