This implies that we'll have to support 6 different kinds of conversions
between path, drive and device, some of which might even be impossible.
Besides, perhaps it'd be cleaner to split this conversion to a separate
tool, so that grub-probe only operates on devices, and the other tool
converts paths to devices (but NOT necessarily devices to paths!).
What does everyone think about this?
