Bugs introduced by source uploads
DLA 2332-2 (sane-backends)  is a regression that happened due to
changing the upload process between the last archive upload and our
first security upload, from a developer arch+indep build followed by
buildd arch builds, to a buildd-only separate arch and indep builds .
It is particularly difficult to catch, because it can only be detected
after the security upload, while our testing (obviously) happens before.
To help detect this ahead of time, I modified and tested the recommended
build procedures at:
to perform split arch and indep builds.
