          Instantiated NixNG configurations.
          `nixngConfigurations` is for specific machines. If you want to expose
          reusable configurations, add them to [`nixosModules`](#opt-flake.nixosModules)
          in the form of modules (no `lib.nixosSystem`), so that you can reference
          them in this or another flake's `nixngConfigurations`.
