it will still generate more work for x86 which will have to calculate one more job at the nej phase

Evaling one Lix should be quite cheap though?

ci currently has issues with some of the changes

the relevant error log(?)

I repeatedly get now

E                   FileNotFoundError: [Errno 2] No such file or directory: 'chmod'

(yes, there's a chmod in the shell available and I killed the entire temp dir before)

so something looks pretty off here

In reply to @commentator2.0:elia.garden
are you using darwin?
otherwise do a just clean & just setup & just install

so, the quickfix to make the test green again:

diff --git a/tests/functional2/testlib/fixtures/nix.py b/tests/functional2/testlib/fixtures/nix.py

this is obviously not what we want, but this confirms that the Command/Env machinery is misbehaving here. No idea why I saw no complaints in the sandbox build though 🤷
