The attribute ‘config.systemd.services.<service-name>.runner’ generates a script that runs the service outside of systemd. This is useful for testing, and also allows NixOS services to be used outside of NixOS. For instance, given a configuration file foo.nix: { config, pkgs, ... }: { services.postgresql.enable = true; services.postgresql.package = pkgs.postgresql92; services.postgresql.dataDir = "/tmp/postgres"; } you can build and run PostgreSQL as follows: $ nix-build -A config.systemd.services.postgresql.runner -I nixos-config=./foo.nix $ ./result This will run the service's ExecStartPre, ExecStart, ExecStartPost and ExecStopPost commands in an appropriate environment. It doesn't work well yet for "forking" services, since it can't track the main process. It also doesn't work for services that assume they're always executed by root. |
