When running ‘make guix-binary.x86_64-linux.tar.xz’ twice (and of course ‘guix gc -d /gnu/store/*-guix-tarball.tar.xz’ in the meantime), one can see that the ‘db.sqlite’ files in the tarballs have the same size but differ by a few bytes.
It’s not clear whether this is an issue inherent to SQLite3 or rather something due to the way we create the database. (<https://trac.torproject.org/projects/tor/ticket/11630> might give some ideas.) Ludo’.
