It 'SHOULD' be good.  We announced it over the same weekend it was broken.

That does not mean every single combination of firmware, hardware, etc
on every possible machine frm every manufacturer will work.  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.
