ah, I think you refer to:

https://github.com/nixos/nixpkgs/blob/9bc093b30a3ab38f9e5b30a132b08a9fd9b27ade/nixos/lib/systemd-lib.nix#L299

That should refer to a new option config.systemd.path, which for boot/systemd.nix and boot/systemd/user.nix should refer to config.path.

thinking about this more. IT could also do in systemd.nix's config section:

systemd.services.*.environment.PATH = mkDefault "${makeBinPath config.path}:${makeSearchPathOutput "bin" "sbin" config.path}";

with some added fiddlyness to handle *

In reply to @elvishjerricco:matrix.org
Yea the fiddlyness for * is the tricky part. I don't know if there's a correct way to do that

I've seen this before:

# foo.nix
{
  options.foo = mkOption { type = attrsOf (submodule <module>); };
}

#bar.nix
{
  options.foo = mkOption { type attrsOf (submodule <more module>); };
}

But I'm pretty sure this wasn't intended to work, and doesn't work anymore (last I checked, like a year ago)
