Why is it important to ignore the label from the boot sector? What is
the situation where if there is not a label in the root directory, and
there is a label in the boot sector, it is the Wrong Thing to return it?

For that matter, aside for a diskette from DOS 3.x (where using the
label from the boot sector *is* the right thing), why/when would we
ever have a label in the boot sector and not in the root director?
