PASSED: Signs of life test

Install additional RMW implementations

STOP Don't do this. I broke the system doing this. I think I ended up with a miss-matched libraries. This must only be related to a Bouncy install. I don't think this belongs in a Dashing install.

Install additional packages using ROS 1 packages

STOP I've gotten into trouble here before. I hope not to need ROS 1 packages through the Bridge. Maybe running everything on the NUC will help avoid this
