Hi Armin,
I'm sure we can dig up lots of details on the zero-outputs case (all
shell protocol interactions could use testing without outputs, I think
there are quite some possibilities for NULL dereferences), and the
output configuration task might turn out fairly big too if we make it
all nice for libweston users. ;-)
But yeah, it's a thought to keep in mind.
That reminds me, we should probably talk with Quentin about how the
output configuration will look like, since I'll be away much of the
time.
Thanks,
