Do not take this offensively, but don't you think it's a little silly to
require a person to mount the storage on another system before
upgrading? Or do you mean that the upgrader would simply be the new
version of the OS, perhaps running off of a CD?
Still, patching an OS shouldn't require a reboot. Not even MS requires
a reboot for most patches anymore.
