I'm really curious what a generalist, functional ROS setup looks like. Because I certainly have never had one.
I'm imagining a collection of something like 15 images, one for each ROS distro, each with their own extremely vanilla ubuntu install, an enormous set of dependency packages frozen in time from 2014 or whenever that distro was released, and every single tool in the ros-extra-extra-extra ecosystem. Also, whatever general environment & python crap was in-vouge at that particular time.
