I don't quite see how that would work - do you mean gpart should
configure a gnop?  AFAIK there is no "gnop label", so you can't set up a
persistent gnop; you have to set it up manually at boot time every time,
and there's a risk that the fs (or other layers higher up) will taste
the underlying device instead of the gnop.
