you run rpm -q grub in the guest and on the host, if they are the same nvr,
then they are the same package, where's the rocket science here.

you can install KDE and GNOME and you are worrying about grub and grub2?

surely grubby could detect which one is actually in use and pick it without the world ending.

but I agree with Mark, you guys are completely conflating two very different things and using
one to justify the other.

the is no technical reason why grub and grub2 should conflict, if there is syslinux should also conflict.

Maybe I have a grub USB key I want to update with a new grub while my main MBR is grub2.
