init-live.sh: distinguish between a read-only image and a read-write image
The iso and hddimg share a common concept of 'live image', and they use the same initramfs and thus the same init. However, that init script in initramfs made a wrong assumption that the rootfs image was read-only by itself. This is apparently not true for hddimg. To make things work as expected, this init script should at least distinguish between a read-only rootfs image and a read-write one. This patch adds this ability to the init script. After this change, the init script would be able to check whether the rootfs image is read-only or not. If the rootfs image is read-write, the image will be mounted and then booted directly. No union mounts will be attempted in this case.
