Package: sbuild Version: 0.65.0-1 Severity: wishlist Tags: patch Thanks for maintaining sbuild!
In order to use sbuild for reproducible builds, the build dir needs to
be consistent across rebuilds, but sbuild currenty generates a
randomly named build dir.
The following proof-of-concept patch does this by setting the build
dir to /build/PACKAGE-VERSION rather than /build/PACKAGE-XXXXXX:

This patch is really only a small step forward, making the build dir
consistent only when building with sbuild. Ideally, the build dir
should be set to /usr/src/debian/PACKAGE-VERSION (or some other widely
agreed upon dir) so that builds would be reproducible if built with
other tools such as pbuilder using the same build dir.
Making the build dir configurable might also help...
live well,
