################################################################################ # # Build the iso96600 root filesystem image # ################################################################################ # # We need to handle three cases: # # 1. The ISO9660 filesystem will really be the real root filesystem # itself. This is when BR2_TARGET_ROOTFS_ISO9660_INITRD is # disabled. # # 2. The ISO9660 filesystem will be a filesystem with just a kernel # image, initrd and grub. This is when # BR2_TARGET_ROOTFS_ISO9660_INITRD is enabled, but # BR2_TARGET_ROOTFS_INITRAMFS is disabled. # # 3. The ISO9660 filesystem will be a filesystem with just a kernel # image and grub. This is like (2), except that the initrd is # built into the kernel image. This is when # BR2_TARGET_ROOTFS_INITRAMFS is enabled (regardless of the value # of BR2_TARGET_ROOTFS_ISO9660_INITRD).
