/** Control whether the GPT partition table is allowed to leave some parts of
the emerging ISO image uncovered, whether the partition entries in the
GPT get sorted by their start block addresses, and whether partition 1
gets created to represent the ISO 9660 filesystem.
Default is that the partition entries get sorted and all gaps get filled
by additional GPT partition entries. Partition 1 is by default created for
the ISO filesystem if partition offset is 16, no partition 1 was created for
other reasons, and no other partition overlaps with the range from LBA 16 to
the end of the ISO 9660 filesystem.
Note that GPT for ISOLINUX isohybrid does not get gaps filled, anyways.
