Motivation for this change

We currently have support for system tmpfiles but not the user equivalents. This PR only enables the units so you can stick files in ~/.config/user-tmpfiles.d and have them work as expected.

A next step would be to:

  1. create systemd.user.tmpfiles.rules similar to systemd.tmpfiles.rules
  2. patch systemd to look into /etc/user-tmpfiles.d instead of /usr/share/user-tmpfiles.d
  3. write out systemd.user.tmpfiles.rules

Cc: @infinisil @fpletz

Works fine here with files in ~/.config/user-tmpfiles.d

Things done
  • Tested using sandboxing (nix.useSandbox on NixOS, or option sandbox in nix.conf on non-NixOS)
  • 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)
  • Assured whether relevant documentation is up to date
  • Fits CONTRIBUTING.md.

@peterhoeg might want to try patching systemd on top of #61321.

The update to 242 is unrelated - we are simply pulling in a few units that upstream has been distributing for a number of releases.

@peterhoeg how are the units supposed to be activated?

They get activated for me automatically on login. The ``--setup``` unit cannot be activated manually.

@peterhoeg we might want to add a NixOS test for that. Could you do that?

In addition, maybe home-manager should trigger user-tmpfiles creation on activation, similar to https://github.com/NixOS/nixpkgs/blob/master/nixos/modules/system/activation/switch-to-configuration.pl#L412
