What were you trying to do that didn't work?

The new release of grub2-common-2.06-80.el9_4.noarch breaks leapp upgrades from RHEL8 to RHEL9 on UEFI: after the upgrade occurs, the next reboot (on RHEL9 kernel) fails at "grub>" prompt.

The reason for this is grub2-common-2.06-80.el9_4.noarch doesn't move /boot/efi/EFI/redhat/grub.cfg to /boot/grub2/grub.cfg anymore but just replaces it with the stub:

# rpm -q --scripts -p ./grub2-common-2.06-80.el9_4.noarch.rpm 
posttrans scriptlet (using /bin/sh):
[...]
mv ${EFI_HOME}/grub.cfg.stb ${EFI_HOME}/grub.cfg

Whereas with older release:

# rpm -q --scripts -p ./grub2-common-2.06-77.el9.noarch.rpm 
posttrans scriptlet (using /bin/sh):
[...]
cp -a ${EFI_HOME}/grub.cfg ${EFI_HOME}/grub.cfg.rpmsave
cp -a ${EFI_HOME}/grub.cfg ${GRUB_HOME}/
mv ${EFI_HOME}/grub.cfg.stb ${EFI_HOME}/grub.cfg
