use-xdg-base-directories does not effect $PATH

[bestlem]

I have set nix.settings.use-xdg-base-directories = true

This means that running nix build .#"homeConfigurations.user@machine.activationPackage" and running the activation home-manager puts things in $XDG_STATE_HOME/nix/profile rather than ~/.nix_profile according to https://nixos.org/manual/nix/stable/command-ref/conf-file

However the path set by nix-darwin includes ~/.nix-profile.bin rather than the XDG one.

Am I correct is assuming that |/.nix-profile should not exist and that the $PATH should include $XDG_STATE_HOME/nix/profile/bin ?

I suspect others are not noticing this as they always use darwin-rebuild with home-manager.useUserPackages = true; so the path is /etc/profiles/per-user//bin which is on the PATH .

I was trying not to have to use sudo each time so I used the build above - should I not be doing that?
