Hi there.
Have a question about nixpkgs per node inside a flake. I'm trying following configuration likewise in manual for a hive:

{
  inputs = {
    nixpkgs.url = "github:NixOS/nixpkgs/7076110064c09f0b3942f609f2134c1358ef2e50";
  };

  outputs = { nixpkgs, ... }: {
    colmena = {
      meta = {
        nixpkgs = import nixpkgs {
          system = "x86_64-linux";
          overlays = [];
        };

        nodeNixpkgs.desktop = ./nixpkgs-23.05;
      };

      desktop = import ./desktop.nix;
    };
  };
}

But it does not work:

error: Passing a path to Nixpkgs as meta.nodeNixpkgs.pc is no longer accepted with Flakes.
       Please initialize Nixpkgs like the following:

       {
         # ...
         outputs = { nixpkgs, ... }: {
           colmena = {
             meta.nodeNixpkgs.pc = import nixpkgs {
               system = "x86_64-linux"; # Set your desired system here
               overlays = [];
             };
           };
         };
       }

Is it possible somehow to pin specific version of nixpkgs for a host in flake configuration?

There is only example for hive.nix:

    nodeNixpkgs = {
      node-b = ./another-nixos-checkout;
    };

I cannot find out where I should place a path to a nixpkgs when using flake
