Hi Johnny,
thank you very much for clarification.
You said that in the centos infrastructure only one server got the problem.
What are the conditions that permit the breakage? There is a particular
configuration (hw/sw) case that match always the problem or it is random?
Thank you
I have two servers running Centos 7 on apple
hardware (one mac-mini and one mac
server). They both failed to reboot a few
days ago. So perhaps whatever anti-boot bug
hit Centos 8, also hit Centos 7. I can't tell
what version got updated since the system
simply fails to boot. I don't even get a grub
screen. I'll have to rebuild the systems from scratch.
You should be able to boot off of installation
media into rescue mode, and downgrade the grub2* and/or shim* RPMs.

This is a good idea, if I knew how to
"downgrade...". But in any event, I had decided
to rebuild from scratch, which of course failed
as soon as I did an yum update. So, I'm
installing 7.8.2003 with no updates until I see
the "all clear -- updates will no longer make
your system unbootable" message from the Centos team.
In my many years of blindly updating my
installations, starting from the free Redhat
distributions, through Whitehat and onto Centos,
this is the first disaster, and luckily, it
didn't hit all my systems. Let's hope there aren't many more.
David
