Doc Text:	Previously, the Red Hat Upgrade Tool was unable to install GRUB 2 when GRUB Legacy was installed. This update fixes the bug, and the grub2 packages are successfully installed during an in-place upgrade. Note that the bootloader still needs to be replaced manually after the upgrade.

Hi guys. I am not able to reproduce described issue with current RHEL 6.10 and packages you mentioned. Please provide me reproducer (ideally machine) where I can see it. From the source code, there are only two ways (that I see) how the issue would occur
- there is not installed the grub rpm signed by RH on RHEL 6 system (notabug)
- the rpm is not available during installation (means, e.g. network failure? or dependency issue because of other installed RPMs - not in the mentioned group of supported rpms) - in such case, this is about completely different problem and possibly notabug as well


Or send me please /var/log/upgrade.log from the upgraded machine. The script that is supposed to install grub2 is (after run of preupg) stored here:
 /root/preupgrade/postupgrade.d/grub/postupgrade-grub.sh

OK, verified semi-manually:  No matter if --no-cleanup-post (or whatever is the name) is used, in both cases grub is correctly replaced by grub2.
