Because... why not?

So the MacOS nix build fails. @robx I think you added that job. I have no way to debug that, could you have a look?

Looks like the build is timing out. In #2615, I added a github workflow that can be triggered manually to incrementally seed cachix -- you could try running that on this PR branch? Possibly it also passes in the meantime with hydra having caught up -- I just triggered a rerun of the failing job.

Aha. How do I do that? When I go to the actions page for this workflow, I can't select my branch. Do I need to create a branch in the main repo instead of my fork? Or do I need to do run the action in my fork instead, setting up cachix tokens before that?

I assume both could work?

Yeah, I think pushing a branch to the main repo is probably the most straightforward way, that's what I did for the last upgrade.

Tried this - worked!

I had a random network failure during the seed-cachix job, which killed all other matrix jobs because of the default, implied fail-fast: true. Will change that to fail-fast: false to allow other jobs to continue.
