reproduce.debian.net

Attempts to bit-for-bit identically rebuild each Debian binary package found in the distribution archive, using the .buildinfo file produced when the buildd originally built the package.

For each distributed package, rebuilderd calls debrebuild that calls debootsnap, mmdebstrap and finally sbuild to build that package within a user namespace.

• buildinfos.debian.net provides .buildinfo files for each distributed binary package. (see #763822, #929397)
• debootsnap uses snapshot.debian.org to retrieve the exact same version of each build dependency package (which was used for the "original build"). (see #1096129)
• The goal is to replicate the same build process that is used by Debian during package publication -- not to seek out additional sources of variance.
• Variance testing, used to find factors that can prevent packages from rebuilding reproducibly, will continue at https://tests.reproducible-builds.org/debian/reproducible.html.
• If you are wondering why we are doing this at all, then hopefully the Reproducible Builds website will explain why this is useful.
