Just because RHEL and Fedora have chosen not to include binary incompatible patches, doesn't mean its a truism across the guest OS landscape does it?
Is that binary compatibility tested for as part of operation? Is that compatibility strictly a consequence of distribution level decision making concerning Fedora and RHEL? Is that binary compatibility guaranteed or promised from other distribution's grub1 variants being shipped?

Like I said, not true. The grub package is designed to be updateable without requiring an mbr reinstall. What's more is I had a look at the stage1.[hS] files in the grub shipped in FC-1 and RHEL-5, and just like I said, they are indeed binary compatible. So even if the grub user space application pulls its MBR from a statically linked copy of the MBR, it will still work with pretty much any stage1.5 or stage2 you find in a guest.
