To be more specific (now that I've dug through the code), grub2 (used by rhel7) uses EFI boot stubs. grub and elilo apparently do not use EFI boot stubs, so they don't hit the problem (at least on my test systems). -- Russ Anderson, OS RAS/Partitioning Project Lead SGI - Silicon Graphics Inc [email protected] -- To unsubscribe from this list: send the line "unsubscribe linux-efi" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
