Yeah, i was using Void but atm i'm using Guix. From what i can tell Guix doesn't have an implementation for it either, but my current setup works so that's good lol. I just have a shepherd service that executes the script in my users' .nix-profile as root. The tmpfiles.d method is basically what this project is doing as well. I ended up not using it because of that, but i also don't like that it adds more projects that you have to depend on to get it working compared to the manual setup that we're doing.
