Okay what distros are we talking about? What’s an example of an unreliable one and what’s a reliable one?
I think it’s much more complicated than this. Honestly there’s a reason it took decades for Linux distros in general to get as stable as they are today. It’s really really hard to build an operating system.
I think a better analogy for installing updates on linux would be riding a motorcycle. Accidents happen all the time. They’re bound to, be prepared. Just because you can ride for 30 years unscathed doesn’t mean you can take that for granted.
