the Debian packages people normally use *are* already reproducible (well, 80-90%
of them, at least), we just don't systematically have the results from included in things like which is being tracked as " tracker.d.o should 
display results of reproducible rebuilds, not just reproducible CI results".

(and beta.t.r-b.o is a bit stalled, and our snapshot lacks non-free-firmware
(and is amd64 only) and the debian snapshot server is not usable for large
scale testing and some other issues: we got new SDDs for our snapshot mirror
but had raid controller issues with those which were only fixed last week etc pp.)

so, cool Debian news: Debian bookworm will quite very probably ship 
debian-live made live images, which (mostly) Roland Clobus made reproducible
over the last year (with the help of our jenkins setup), so there's
that and that's also not yet been announced, because it's not ready yet. :)

there's more: mmdebstrap and friends now can create reproducible chroot tar archive
or docker container and someone should rebuild those latest debian-installer
releases to see if those are reproducible...

YES. to every word here.

thankfully we'll have both a Debian release and a DebConf soon, which in
the last have been occassions were we summarized things and updated
where we are and want to be.

so stay tuned.
