A reasonable action, but that doesn't mean you know what you are doing. I also recognize you stated you have been using Linux for a long time. However, duration does not always equate to experience.

First, that is factually untrue. Second, is it a user-spaceapplications breaking your system? If not, it isn't relevant to your argument. If it is, the program wasn't architected properly, and you should get rid of it.

Of course an OS requires constant effort to keep running. That is the nature of computing. Name one OS in the world which doesn't push security updates (which is still supported). You can't!

Honestly, even when things do manage to go sideways, you should have disaster recovery plans implemented. There is no reason you should have to nuke and pave every time something goes wrong.
