Hmm, the several special cases / hacks here maybe suggests some generalization is needed? Also, for X, there is typically a .xinitrc, .gnomerc, or similar that's executed as a shell script during system launch. Do we have plans for adding something similar for weston? Like a .westonrc? If not, perhaps this feature gives us a place for hanging startup scripts? (Not saying that shell scripts are the best way to do autostart of applications, but it has been a tradition...)
