I wouldn't consider something that needs to go into a special, unusable mode to apply updates and restarted after to be that resilient. I usually apply many an update to my laptop (running Kubuntu) while using it, and even ignore the occasional restart message (after a kernel update), as it's just a recommendation that can be deferred indefinitely, and my system still remains stable. And my uptimes tend to be on the order of months. Now that's resilience IMO.
