The only problem I can see with this is if one of the more exotic disk=20 controller drivers or file systems drivers goes homicidal (diskicidal?).=20 Booting multi, you will automount all your big disks and arrays giving the= =20 drivers the chance to wreak havoc before you can do much about it. This see= ms=20 pretty unlikely on -STABLE though. You're still in trouble though because=20 you've probably lost / which probably contains the backup of the old kernel. In conclusion, its probably best if disk controller drivers and filesystem= =20 drivers don't have bugs in them.
