Yes, I mean "yes" to multiple instances: the root's Shepherd can't
handle user services, you need to start another (user) Shepherd for
that.  Knowing which instance you are talking to is easy:

- when you run "herd" command as root, it talks to the root's Shepherd
  (on GuixSD its socket file is "/var/run/shepherd/socket");

- when you run "herd" as user, it talks to the user running instance
  (its default socket is "~/.config/shepherd/run/socket").
