Oh, thats not what I meant. I don't want UML to skip bounds checking, I just
want it to notice when the bounds change.

ie, if for example I handed a logical volume to UML as db0, and I resize that
(on the host, using LVM), I would want UML to notice without having to
completely restart it, so I can use resize_fs inside UML too.
