In some comments about the multiple-distro setups there were rather
vague references to occasional syntax problems between different
distro's versions of grub. I don't know if it was due a change that
was introduced upstream when grub was updated or some sort of RedHat
custom-feature-backporting-bastardization.

I thought that's what LVM provided was a drive definition.
