So, Philipp Kern dropped by asking if we could do some #ReproducibleBuilds verifications of recent Debian Security updates, given, well the whole #xz mess... and that our build infrastructure may have run compromised code at some point...

So I did a quick pass at a handful of updates and everything verified ok so far, though I skipped some of the probably more juicy targets such as chromium and firefox:

Debian is reproducible enough to at least try this sort of thing!
