Robert Collins cb62bae9b8 Build images using loopdev instead of qemu-nbd. 
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.

README.md

Sets up a partitioned disk (rather than building just one filesystem with no partition table).

The disk will have grub[2]-install run on it, and that assumes a functional grub[2] setup.
