Which is basically what sourcerer acomplishes in a nice, transparent,
round up fashion (upload pending some spare time).

sourcerer-archive maintains a local archive of selected sources and
packages from various sources (debian mirrors or incoming
queue). E.g. mirror all installed packages and sources.

sourcerer-watcher watches for apt activity and can update the
selection of sourcerer-archive automatically. On "apt-get install
foobar" foobar gets added to the package list, on purge it gets

sourcerer-buildd finaly builds selected packages from the archive and
uploads it to the archive again. Local gcc options can be enforced,
e.g. to optimize for i686, and the version is modified bumping the 4th
part of the debian revision (debian only uses 3) to generate a version
higher than this one and lower than any debian upload.

With this and apts pining it is trivial to install and update a system
with only locally build debs or with the prebuild debs as fallback for
the first install or as fallback for anything yet unbuild or build

This also has one big advantage over apt-get install from source: You
do not have to wait for the compile to finish. The nightly cron job
will start the build and the new debs will be ready for install in the
