This enables a module system feature documented here: https://nixos.org/manual/nixpkgs/stable/index.html#module-system-lib-evalModules-param-class For example, it allows a mistake to be caught, which is loading a NixOS module into home-manager. This only works when the offending module declares what it's for with a `_class` attribute. It is not expected that users declare the `_type`, because the payoff is small. It is only expected to be set by generic code, such as functions or libraries that help with the "publishing" of modules (e.g. flake-parts, flake-utils). The class feature has been available in the module system since https://github.com/NixOS/nixpkgs/pull/197547, merged May 6, 2023. It has been part of all releases since 23.05-beta. The last NixOS release that did _not_ support it has been end-of-life for close to a year now. Example: (lib.homeManagerConfiguration { pkgs = nixpkgs.legacyPackages.x86_64-linux; modules = [{ _class = "nixos"; imports = [ ./foo.nix ]; }]; }).activation-script Corresponding error: error: The module <unknown-file> was imported into homeManager instead of nixos. (`<unknown-file>` can be improved by also setting `_file`, if known; a much older feature) PR #5339 |
