It looks like devd uses a config file, so xfsettingsd would need to add 
an entry to that. In any case, I don't have a BSD system to test on. How 
about if I #ifdef this to work only on Linux and if someone else with a 
BSD system has the time, then they could add the feature in? We could 
instead use X11, but then we are writing new code that we know will 
eventually die, which seems like bad design to me.
