Package: sbuild
Version: 0.88.1
Severity: normal
X-Debbugs-Cc: sramac...@debian.org

I am using a sbuild+schroot setup (unmodified schroot config, sbuild has
purge_build_directory set to "successful"). That means that
/var/lib/sbuild/build is mounted as persistent /build. Consequently,
when you do:

$ dpkg-buildpackage -S
$ sbuild $dsc

and repeat this step without changing the version number and a build
fails, sbuild will continue building the failing version even if the dsc
changed. dpkg-source fails to unpack the new source packages as the
target path already exists:

$ dpkg-source -x libmpc_0.1\~r495-3.dsc
dpkg-source: warning: extracting unsigned source package (libmpc_0.1~r495-3.dsc)
dpkg-source: info: extracting libmpc in libmpc-0.1~r495
dpkg-source: error: unpack target exists: libmpc-0.1~r495

But sbuild does not seem to check the exit code of dpkg-source and
continues with the build.

Let me know if you need any more information.

Cheers
