nixpkgs config is not passed from global blueprint configuration to hosts

[Yethal]

Describe the bug

Regardless of which nixpkgs options I declare in blueprint they are not passed to any of the hostd

To Reproduce

Steps to reproduce the behavior:

1. Navigate to templates/nixos-and-darwin-shared-homes
2. Run nix flake show (no issues as expected)
3. In modules/home/home-shared.nix add any unfree package to home.packages
4. Run nix flake show again (nix refuses to evaluate, as expected)
5. Add nixpkgs.config.allowUnfree = true; to blueprint invocation
6. Run nix flake show again (nix still refuses to evaluate)

Expected behavior I expected blueprint to pass the nixpkgs instance to hosts the same way it does for homeManager

System information

Additional context Modified value is visible in homeConfigurations under outputs.legacyPackages.x86_64-linux.homeConfigurations."me@my-nixos".config.nixpkgs.config but not visible anywhere under outputs.nixosConfigurations.my-nixos so it seems like passing nixpkgs just doesn't work for some outputs at all.

there are so many issues with this, it should be disabled for now...

Having the same problem. First day using blueprint, I thought I was crazy

Is there a workaround for this? Because home-manager refuses nixpkgs.config.allowUnfree = true when useGlobalPkgs is true, and I would prefer to not disable this one.

@calops This actually works fine with home-manager, it's nixosConfigurations that do not pick this up

[calops]

You're right, my bad. I was confused by the poor error messages.

Note that nix-darwin also doesn't pick up on this but that's probably not surprising. It's an easy workaround in the meantime.
