Quoting http://www.syslinux.org/wiki/index.php/Isohybrid#UEFI:

"The additional isohybrid feature for UEFI adds a partition to the MBR
partition table pointing to the same file in the ISO 9660 filesystem
as does the El Torito catalog entry for EFI."

According to this (and can be see using fdisk) it's being created a
partition-inside-partition just by setting its start and end sectors,
so this could be done to be equal to the initial MBR partition
generated by IsoHybrid, so there would not be duplicated files
(kernel, initram and syslinus.cfg). Is that possible, currently or
with some patches on isohybrid command? In what situations it would
not work (iso9660 can be seen as a read-only FAT filesystem)? Also,
could it be used directly the same MBR entry just by setting the
partition entry flags or with some other minor tune-ups?
