<nixos/lib/eval-config.nix> not honor modularily set
nixpkgs.pkgs for use in the
pkgs arguments of modules?
is not set on the caller?
When evaluating a modularily set version of packages with an eval config of a different version, then I get an evaluation conflict, for example here:
giving proof of en environment in which the module’s
nixpkgs is based on the new version while
pkgs is an old version.
If I use
eval-config.nix off the same version, then there is no version mismatch.
I can’t see where
eval-config does this magic (in the case that it’s own
pkgs argument is
I’m parsing this
to be evaluated to
 in this case.
Next, I’m parsing that this
would set it to my modularly set pkgs version.
But the error suggests there is at least one instantiation involved with a version mismatch. Why?
Is laziness broken?
