I did another round of this...

I fixed a few packages recently, and noticed some other people fixing
packages too, yay!

As of this moment for x86_64, it looks like:

* ~83% matching (a.k.a. reproducible) for 18920 packages
* ~6% not matching (a.k.a. NOT reproducible) for 1337 packages
* ~11% unknown (e.g. not built on both build farms) for 2440 packages

  https://data.guix.gnu.org/repository/1/branch/master/latest-processed-revision/package-reproducibility

Ignoring the pesky unknown packages, it is more like ~93% reproducible
and ~7% unreproducible... that feels a bit better to me!

These numbers wander around over time, mostly due to packages moving
back into an "unknown" state while the build farms catch up with each
other... although the above numbers seem to have been pretty consistent
over the last few days.

More like ~570 out of ~1300 this time.

Apparently there is an upstream issue for ecl, which is referenced in
the summary.

>   * ~850 packages categorized (ecl-* accounting for most of them)

~990 packages reviewed (many duplicates from previous run). Slightly
higher number to review higher this time, mostly due to some previous
unknowns being reproducible/not reproducible.

There are a handful of older-versions of things (e.g. package@1.0 vs
package@2.0) that fail to build reproducibly and I didn't bother to
look, I only checked the most recent versions of packages, so there are
probably 300+ packages that could be reviewed.

Still true!

I tried patching texlive directly and failed to come up with something
that worked, but haven't tried again recently.

Did a little of this, but still more to do!

Still very true! Maybe I should arrange a little virtual hackfest or
something...

I should probably normalize these issues a bit more and simplify them,
but the full list I looked should be attached.

Would it be ok to maintain this and some of the relevent tooling in a
branch in guix.git, say, "reproducibility-notes"? Or make a new
repository just for this? It most likely wouldn't share history with the
other branches (much like the "keyring" branch), but presumably won't
grow too large either.
