bug#50860: Core-updates-frozen world rebuild coordination

[John Kehayias]

Hi all,

Thanks for coordinating this Leo. Is there anything else with huge rebuilds to 
push together?

I don't want to keep finding and adding things, but two possibilities come to 
mind that I've just noticed:

1a. p11-kit #49957 https://issues.guix.gnu.org/49957

I've just hit this bug on core-updates-frozen as well, though was originally 
reported on master. As I noted there, I tried to test with just grafts but 
didn't fix it for me (I'm guessing grafting won't work with that configure flag 
change). The patch matches how nix configures p11-kit as well, due to this bug.

1b. p11-kit is also now out of date. The changelog doesn't look substantial or 
serious, but given the nature of p11-kit I wonder if we want to update it now 
too. https://github.com/p11-glue/p11-kit/releases/tag/0.24.0

2. (minor) Mesa has had a few more bugfix and major releases since my initial 
patch for core-updates-frozen. Now at 21.1.8 for the 21.1 branch (we have 
21.1.6 currently), but 21.2 has also had stable releases, with 21.2.2. I 
previously built 21.2.1 and sent a patch for it, and could test 21.2.2 if we 
want to do that too.

I'm aware this could continue forever, and #2 is likely lower priority. #1, 
though, should we consider p11-kit a critical update (version, at least) since 
we're still fixing core-updates-frozen?

Thanks everyone!

John
