Records that a mountable ISO 9660 root was called off -- the ISO already
boots a complete system from the ramdisk, so it is the live environment
and an installer makes a mountable disc redundant, which drops the ATAPI
driver and ISO 9660 filesystem entirely.
Also records the installer's shape (both firmwares from the start, .sip
before anything installs), the five-stage dependency chain, and the 4 GB
limit the raw block device carries.
