Jesse Pretorius 329aa472f2 MNAIO: Enable saving and re-using file-based backing images
Being able to save the images and re-use them on other hosts
is extremely useful to cut down deployment time. This patch
allows an MNAIO setup to be setup using a file-based backing
store, then have those saved and re-used on the same host or
on other hosts.
