If *anyone* has the answer to this, I want to know. Or maybe we should
just file a bug against parted, which ABSOLUTELY, POSITIVELY does *not*
want to a) align it for best performance, or b) *TELL* you what you need
to align it.

Using gparted (GUIs, why did it have to be GUIs), you at least don't get
that idiot warning.
