My apologies. That may have changed with SIP. A _fully optional_ feature that is great for security, and can be turned off if its too prescriptive.

A little disappointed to see the apple hate on this thread, especially as I spent the morning fighting with debian install on a raspberry pi to just have a clean upgrade. Again, these linux issues are much less common when dealing with linux on a server, meant to run a single program, or collection of production programs. But trying to maintain an ubuntu desktop is not without work, and Windows is loaded with telemetry and ads.
