I haven't tried for Debian stable but as I mentioned, for testing and
unstable the debs are working fine.

I'm installing Debian (or Ubuntu) as normal, add ROS to the sources,
install it and you are done.

Why would you allow users to erase or recompile packages? The concept
is, that you have one system installation and users create overlays with
what they need in addition.
