Comment # 7 on bug 1177009 from Neil Rickert

I am adding Michael Chang to the CC list, because I think he maintains grub.

Current situation:

grub2-i386-efi version 2.04-lp152.7.15.1 is broken.  The fix is to install the
previous version (2.04-lp152.7.12.1).

In Tumbleweed, verson 2.04-17.1 is broken.  To fix this, I installed 2.04-16.1,
which I found in the history archives (I think for 20200915).

In both cases, the broken version of grub2-i386-efi will boot the Tumbleweed
5.8 kernels, but fails to boot the Leap 5.3 kernels.

In response, I am changing my testing procedure.

Previous testing procedure:
 When I see that this package is updated, I run:
  grub2-install --target=i386-efi
 and then I checked whether it would boot the system.

New testing procedure:
 When the package has been updated:
   cd /boot/grub2
   rm -rf i386-efi.old
   mv i386-efi  i386-efi.old
   grub2-install --target=i386-efi
 and then check that it can boot both Tumbleweed and Leap 15.2

Moving the directory is to allow easier recovery in case of problems.

Note that all of my test is in a KVM virtual machine.  I do not have a physical
machine with this firmware, but such machines do exist.

I'm guessing that I'm probably the only person routinely testing this package
when it is updated.
