I was trying out the Diamondback Beta on my macbook and I started out trying the desktop-full variant. I noticed, however, that this doesn't pull in the rx and documentation stacks (doesn't extend the rose-full variant). I was wondering if this was intentional. I solved the problem in the short term by rosinstall'ing the ros-full variant to pull these in. The reason I ask is that desktop-full pulls rviz, but rviz seemed to need the rx stack to compile...
