I’m starting to sound like a broken record but since nobody else has mentioned it yet: atomic/immutable distros often use something called rpm-ostree, which stages updates for the next boot. Updates are “atomic”, so you can’t end up with a corrupt partial update, even if you pull the power mid-update (in which case it will just stay on the current version). Everybody gets the same base image, so your OS won’t diverge over time and end up like some frankenstein mess that. It’s all super cool tech.
