At this point, I think I have something demoable. Ensuring Reproducible
Builds is a big task and I want your feedback, ideas, code and support.

In openSUSE we have reproducible binaries to a certain extend. That
project was started some years ago with different (non-security)
intentions. Since the build service rebuilds packages automatically
if any depending package changes, a way was needed to avoid publishing new
rpms if the build result result didn't actually change. So there are
now some scripts that automatically run at the of a new build and
determine with some heuristics whether the new rpms match the old
rpmsĀ¹. You can see the output of that script in every build log in
openSUSE:Factory.

https://build.opensuse.org/package/show/openSUSE:Factory/build-compare

These scripts look great. Thanks Ludwig!

Hopefully, we can re-use them in Fedora.
