Nor am I; that's why I have testing server VM's on which to stage updates.  Even on the production servers, thanks to them being VMware guests I can pull a snapshot prior to doing the updates, and if the update breaks things badly enough I can roll back the snapshot from VMware and triage the problem.  Updates should never be blind, IMHO, especially for production servers.

That's also why I keep regular backups of my laptop; in that case I'm tracking Fedora (although I'm seriously considering purchasing RHEL Workstation), and even then I have a test desktop to see if anything major breaks.  While the test desktop is not identically configured, it is close enough to be a valid test case, all the way down to the nVidia graphics.
