Dropping the patch tag because the patch is incomplete (although likely
to be along most of the right lines).

apt-build needs to update the configuration string which it passes to
apt, along the same lines as recent updates in multistrap, xapt and
other tools which use apt in custom locations.

This is another instance of #637434 and may well need a similar patch
which can be seen in Emdebian SVN:

AFAICT if the test system does not use a Default-Release, this bug
won't occur. apt-build *might* have to assert unstable as the
Default-Release or try to replicate the system setting somehow. I don't
use apt-build.

apt-build should do this anyway. xapt has a similar --clean option
explicitly to do this kind of thing. If it doesn't, this would warrant
another stage to the patch or a new bug report (severity important).

No, it will still be an apt-build bug. The question is what do you
expect apt-build to do if Default-Release is set on your own system?
Build for unstable (Debian expectation) or build for whatever is the
Default-Release on your system?

Once that is decided, the final tweak to the patch should be fairly

apt-build is an orphaned package (and has been orphaned for a v.long
time) and has no maintainer. If you're doing this much work on
apt-build, maybe you should read the orphaning bug (#365427) and see if
you can work with those who have also expressed an interest but not
actually made the upload as maintainer. Maybe even form a team.

Otherwise, once the Wheezy freeze starts, apt-build could well be
