But, we >have had no reports of failure since the updates. Ummmm.............. except for apple hardware. My Mac-mini runs just file as long as this text: exclude=grub2* shim* mokutil is added to the end of the file /etc/yum.conf and executing yum -y update and rebooting works just fine. HOWEVER, if I remove that 'exclude' line from yum.conf, run 'yum update', and then reboot, the system is unbootable. I end up with a blank screen, no grub anything. I have also been unable to recover from this. Therefore, that exclude line stays. I'm sorry about the delay in responding; I wanted to verify this on a 'crash-and-burn' MacMini. David
