I believe this is a better fit for the diskimage type with proper partitions. I don't have data regarding performance of a loop mounted filesystem versus a proper block device, but my gut feel is that using block devices for large partitions will provide a better experience. If we did want to allow for the use of the entire disk, we should find a way to do so without bloating the image files themselves with empty filesystem space. Does anyone know if we can use sparse files to accomplish this with rootfs.img?
