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.
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.
Do you have hardware idling? Because, for sure, Debian rebuilding Debian is superb and it's something we've been working on for years!
Yet we still want more: we also want independent rebuilders, and we want them in a
diverse variety of setups and settings...!
And then we'll want anyone to be able to act on this data too.
How to evaluate a trixie system
sudo apt install debian-repro-status ; debian-repro-status
(Because we only test trixie right now, results on unstable and forky will vary.)
