Stand up a public rebuilderd instance for Fedora rawhide
Yet another build system in fedora-infra? Can the rebuilderd be adjusted that
it submits builds to Copr?
That is a good question. Does copr support running a build with a
specified "$lockfile", i.e. with a fixed set of nvra's? It would also
have to download those rpms from koji, since they are not available
on mirrors.
rebuilderrd is an complete project that does things in its own way.
It turned out to be not-very-complicated to teach it to use a build
script that does the build locally.
Rebuilderd isn't much of a build system but more an orchestrator, it
scans a Fedora repo's metadata for new packages and queue's them up for
building.
Rebuilderd-worker picks up build tassk from the rebuilderd daemon,
executes an arbitrary rebuild script with the to be rebuild rpm file and
reports back a status to rebuilderd.
Additionally rebuilderd provides an API which includes the
reproducibility status of all packages and an optionally diffoscope
output of a non-reproducible package. This could be integrated in koschei?

The worker executes any arbitrary script so definitively this can be an
API call to for example koji. This would complicate things a bit when
the network is unstable.
The main benefit of having rebuilderd being operated separate is that
multiple parties could rebuild Fedora and their results can be compared.
Arch Linux for example has multiple independent rebuilders and a simple
tool arch-repro-status to inspect the reproducibility of your system
installed packages by querying different rebuilders. [1] [2]
