[Why] We now need auto install iso to the specific disk of testbox, so in order to avoid conflict with rootfs_partition, we support a new field for local disk: rootfs_disk.

We need a detailed design document on how rootfs_disk is going to be used, the full usage scheme.

ok, i'll work on it.

-------- Thanks Yu Chuan

Thanks, Fengguang
