One specific case does come to mind. Some unfortunate users will have MBR drives stuck in a partition layout where creation of new partitions is a limited thing, maybe they don't have an extended partition, and it's somehow too late to change it - or anaconda can't handle creating the new partition, anecdotal report here only - and they want to boot another linux-based OS too. Oh, and they're really attached to the idea of /boot outside of /, or they're attached to the idea of a separate /home, so they want to use the one possible new partition as a PV and reuse the existing /boot. I have a suspicion that disallowing reuse of /boot is going to hit a lot of people who are finally getting the gumption to move away from XP on their old systems and are shopping around for a distro to replace it. It's an edge case, sure, and likely a self-inflicted one, but there's probably a whole lot of impoverished schools or users that are just stuck there for whatever reason, and I'd hate to see Fedora burn them or turn them away. -- -- Pete
