scripts/qemustart
using squashfs results in a "no space left on device" error. You need to
manually extend the new build with a tool like dd.
This patch adds the --extend-squasfs parameter to enlarge the image to
64MB. The (64MB - 20MB =) ~44MB free space will be used by the
overlayfs.
This approach is very simple and resets the overlayfs if used twices.
