If that is true, then why does it happen to me?  Why didn't the upgrade
work last time, and why does a simple "yum update" try to trick me into
upgrading, and why does booting fail after that?  There isn't anything
special here.

Besides, it might just work when I actually try to upgrade.  That still
won't explain why running yum update messes up the booting.
