| Build a bootable ISO9660 image. By default, the root |

| which means the root filesystem will be read-only. It |
| requires ISO9660 filesystem support and CDROM support in the |
| kernel. |
| |
| However, if BR2_TARGET_ROOTFS_INITRAMFS or |
| BR2_TARGET_ROOTFS_ISO9660_INITRD have been enabled, the |
| ISO9660 filesystem will only contain a kernel image and |
| optionally an external initrd image. In this case, the |
| filesystem being in RAM, it will be read/write. No ISO9660 |
| or CDROM support is needed in the kernel. |
