That’s not an accurate portrayal of anything though. You’re implying risk management means you’re accepting that the system sucks and the only way to keep it running is to have a backup system.
That’s not what anyone is doing. They are acknowledging the flawed nature of software and humanity in general and guarding against the consequences of this. It’s being smart. Name one distro that has never broken with updates? You cannot because there obviously couldn’t exist one.
