This flag sounds familiar. I do think it solved my problem last time.

Googling a bit- it’s also unclear to me if this bug was solved in mainline Nix itself?

If this Lix changelog is mostly comparing itself to Nix 2.18, I’m curious how many other changes are already in Nix 2.22. It’s kinda confusing
