This is one of the reasons I am not a fan of uptime worship. It's not a stable system until it's able to cold boot.
Say you have a system that has been online for 5 years continuously until a power outage knocks it out. When power is restored, the system doesn't boot to a working system. How far back do you have to go to in your backups to find a known good system? And this isn't just about hardware failure, it's an issue of configuration changes, too.
