Ifstate is now in the release candidate phase for V2 so I am preparing to upstream the nix module to nixpkgs. The question is if the options should be under networking.ifstate or services.ifstate or somewhere different? That's how it's currently done in my flake: https://search.nüschtos.de/?scope=IfState.nix

Services.ifstate might not be optimal because it's not a daemon and only runs on boot or rebuild
