I have two computers running in my ROS network. I only want to update ROS and all its packages on the master computer while the slave just gets a NFS mount of /opt/ros and my ros workspace(the slave is basically a clean linux install without anything prior to the mount). This way, I can guarantee that both master and slave are running the same version of everything, even the source code.

However, it doesn't seem as simple as that. I'm getting some missing module and library errors. Are there some other directories that I need to mount to make this work?
