I repeatedly get now

(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
index fa459c41a..9edb9a60b 100644

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 🤷
