With any type, "show_status" will print what is known about the loaded image

Some boot images contain a boot info table, which needs to be patched when
the boot image gets newly introduced into the ISO image or if an existing
image gets relocated. This is automatically done if type "isolinux" or "grub"
is given, but not with "any".

An existing boot image of type "isolinux" can be discarded or it can be
patched to match its relocation. In the latter case the resulting ISO image
stays bootable if the boot image was really produced by ISOLINUX.

"discard" gives up an existing boot image.
"keep" keeps or copies an existing boot image unaltered.
"patch" applies boot info table patching if an existing boot image
gets copied to a new location.
"system_area="disk_path copies at most 32768 bytes from the given
disk file to the very start of the ISO image. This System Area is
reserved for system dependent boot software, e.g. an MBR which can
be used to boot from USB stick or hard disk.
Other than a El Torito boot image, the file disk_path needs not to
be added to the ISO image.
"partition_table=on" causes a simple partition table to be written
into bytes 446 to 511 of the System Area. It shows a single
