This means that the BlockBackend should not own the DriveInfo. The
backend and frontend need not know of the object that mixes concepts
from both of them. Instead, the DriveInfo can instantiate itself into a
BlockBackend and the board can (if required) use the frontend parts of
DriveInfo to instantiate a device and connect it to the BlocKBackend.
In Kevin's idea there would be no ownership either way. Until then, I
think my patch actually gets us closer to the ideal.
