+1, NixOS makes working with systemd a breeze. Defining units in Nix beats wrangling INI files.

  systemd.services.sync-recyclarr = {
    serviceConfig.Type = "oneshot";
    path = [ pkgs.podman ];
    script = ''
      podman exec -it recyclarr recyclarr sync radarr
      podman exec -it recyclarr recyclarr sync sonarr
    '';
  };
  systemd.timers.sync-recyclarr = {
    timerConfig = {
      OnCalendar = "daily";
      Persistent = true;
      Unit = "sync-recyclarr.service";
    };
    partOf = [ "sync-recyclarr.service" ];
    requires = [ "podman-recyclarr.service" ];
    wantedBy = [ "timers.target" ];
  };

No. Is that not readable to you lol? I think anyone with even a passing familiarity with systemd would understand what that chunk of Nix is doing.

Compare it to the alternative of using plain systemd (including command(s) required to enable units).

Also, consider what build-time validation you get prior to starting the unit/timer. Hint: zero.

Have you been defining them directly in your flake.nix file? I too am on nixos but I keep all my configurations in their native format and symlink them with nix, that way I can take and reuse that config on a non nixos system easily.

The problem I have found is that nixos doesn't seem to pickup and run systemd timers and services placed into the ~/.config/systems/user folder and additionally things like WantedBy=default.target have no effect.

So after I restart all my services manually on reboot I agree, systems timers are cool.

I define all units in Nix because:

a) It is way nicer and you get decent validation at build time

b) A LLM can port units over if the need arises; it’s a very light abstraction around systemd syntax

c) I personally don’t see how I would ever move to another distro :)
