With newer AOSP environments, the system partition is used as rootfs, and there is no initrd in the boot.img.
Unfortunately abootimg -x seems to fail in this case:
/home/jstultz/noinitrd-boot.img: ramdisk size is null
/home/jstultz/noinitrd-boot.img: not a valid Android Boot Image.
Probably need to adjust the code to not make a null ramdisk size a fatal error.
