I mean linux updates are everything but seamless, it highly depends on your exact config and distro, certain hardware configs break every single kernel version, hell even Nvidia would break they drivers super often not even that long ago. Smaller vendors with closed source drivers were even worse. Software just breaks sometimes no matter the amount of testing that you do. It's better just just accept that and deal with it when it comes up. And in my experience (mostly server linux, client Windows/macOS) the worst updates are still macOS, they take for ever to install. Linux and Windows seem to at least install quickly, like a full upgrade takes less than 20 minutes on both, while a minor release for macOS will make my MacBook try to lift off like a jet engine for 45 minutes.
