Seems to be related to the homedir not being defined for the service maybe?

Maybe related to nix-community/queued-build-hook#9 but unsure

[raboof]

indeed adding:

  systemd.services.async-nix-post-build-hook = {
    environment.HOME = "/var/lib/async-nix-post-build-hook";
  };

fixed it, let's keep this issue open until upstream fixed this or we documented it.
