Motivation for this change

Use upstream systemd service file, reducing maintainer overhead.

Note: powerdns no longer runs inside a chrooted environment. This seems to be
against the policy of the upstream developers [link].

Things done
  • Tested using sandboxing (nix.useSandbox on NixOS, or option sandbox in nix.conf on non-NixOS linux)
  • Built on platform(s)
    • NixOS
    • macOS
    • other Linux distributions
  • Tested via one or more NixOS test(s) if existing and applicable for the change (look inside nixos/tests)
  • Tested compilation of all pkgs that depend on this change using nix-shell -p nix-review --run "nix-review wip"
  • Tested execution of all binary files (usually in ./result/bin/)
  • Determined the impact on package closure size (by running nix path-info -S before and after)
  • Ensured that relevant documentation is up to date
  • Fits CONTRIBUTING.md.

Align with upstream systemd service file. journald already stores the timestamp anyway.

Is there a reason why the upstream unit file is not being used?

@rnhmjoj Because nixos modules are written by hand.

Am I missing something really obvious here? 😕

Yes, but I think you can use units installed by a package. If I remember correctly syncthing does it.

EDIT:

Looking at these commits it seems all you only have to do is:

systemd.packages = [ cfg.package ]

provided the package exports a unit file.

A little more work is needed to handle the configuration correctly, testing needs to be redone, ...

@rnhmjoj Thanks for introducing me to the systemd.packages option.

I didn't notice the --config-dir=${configDir} at the end of the line: It looks like the ExecStart still need to be written manually.

Just add set ExecStart in the NixOS module and it will override this option in the provided unit file as well.

Thank you for your contributions.

This has been automatically marked as stale because it has had no activity for 180 days.

If this is still important to you, we ask that you leave a comment below. Your comment can be as simple as "still important to me". This lets people see that at least one person still cares about this. Someone will have to do this at most twice a year if there is no other activity.

Here are suggestions that might help resolve this more quickly:

  1. Search for maintainers and people that previously touched the related code and @ mention them in a comment.
  2. Ask on the NixOS Discourse.
  3. Ask on the #nixos channel on irc.freenode.net.

Ooh, I had completely forgotten this PR, sorry. It's still relevant, can you rebase your changes?
The notice should be moved to 20.09.
