This package recently caused us some very large headaches when it
was updated for a security issue. It is completely unnecessary and
should be removed.
Note that we have recommended that it be removed from the cloud images
in launchpad bug #1227425.
fixes bug #1227420

Qemu-nbd does not perform well with older versions of qemu due to
the lack of writeback caching mode. It also only builds qcow2 images
and there is a desire for raw image support. Finally, qemu-nbd makes
it very difficult to build images concurrently due to the somewhat
opaque nature of how it selects a /dev/nbd# device. losetup, on
the other hand, makes this process very straight forward.
