This should not be used since there is already (or there was) a virtual
provides like that added automatically. Besides I don't find it very 
adapted to the case at hand.

I think that service() could be reserved for daemons waiting in
the background. Maybe the display managers qualify for that, especially in a 
fast user switching world (when serving xdmcp they do, but in that case 
there is already the server(xdmcp) virtual provides).

Using service(graphical-login) has the advantage to be more general,
the disadvantage to be less precise.
