Had a chance to take this for a test run, and it appears to work, though
with a few surprises...

  dpkg-buildpackage -- hello_2.10-3.dsc

Ends up regenerating the .dsc, as --build=any,all,source by default
... which may end up with a different .dsc checksum in the .buildinfo
than .dsc that was passed on the commandline. Which makes some sense,
but maybe would be better to error out? I would not expect to regenerate
the .dsc if you're passing dpkg-buildpackage a .dsc!


  dpkg-buildpackage --build=any,all -- /path/to/hello_2.10-3.dsc

Fails to find the .dsc file, as it appears to extract the sources to
hello-2.10 and then expects to find ../hello_2.10-3.dsc


All that said ... this seemed to work for me:

  dpkg-buildpackage --build=any,all -- hello_2.10-3.dsc

So yay, progress! Thanks!


All of the above cases do not clean up the hello-2.10 extracted from the
.dsc file, so re-running any of the above need to manually clean that or
run from a clean directory or experience various failure modes with the
existing hellp-2.10 directory.


So a few little glitches, but overall this seems close to something we
have really wanted for reproducible builds! And just for good measure,
thanks!


live well,
