GRUB 2 becomes the default bootloader in Ubuntu 9.10

Calling it solved is a bit bold - that xfs_freeze hack has the tendency of freezing - indeed - the whole box solid, provided that system has / (including /boot) on XFS and an unsuspecting admin tries to run grub-install. That hack might work when run from d-i, but in a live system (let's say, after upgrading from etch to lenny and pondering whether it may be time to finally replace LILO) it's a disaster. It should at least print a big fat warning before actually freezing a live FS that might have plenty of write activity.
