This will probably be insufficient, as there are other kinds of failing tests; see eg. #55945 (comment). I don't know if anyone has figured out a common cause yet, but if not, we should probably just disable the tests entirely so as to not break builds?

Even if it's insufficient, people are still having difficulties on it in a non-deterministic manner

Right, I get that. My point is that those non-deterministic issues aren't solved by the current changes because they occur in other tests as well.

other than submitting an issue upstream, which some may be nixos specific, I'm not sure what to do

@joepie91

Disabling the install check is the workaround I've applied locally to make the build succeed, and perhaps that'd be the right thing to do here, at least until the root cause gets fixed.

It's perhaps a bit rigorous, but given that the failures occur in various completely unrelated tests, I'm not sure there are any other options - it looks to me like the problem is in how the tests get run (unintentional concurrency?), not in any one specific test, and so any non-concurrency-safe test might fail.
