Hi,
i closed this bug report because the libisofs fix is released since
nearly four years.
Summary of remaining issue:
The isohybrid layout as defined for ISOLINUX bootable ISO 9660 images
regularly works by the MBR partition of type 0xef, not by the GPT partition
which carries the type UUID of EFI System Partition.
This is well compliant to UEFI specs. E.g. UEFI 2.4, 5.2.1 "MBR".
Under these specs, the GPT and its backup are just opaque bytes of no
special meaning to UEFI, because the MBR is not "Protective".
GRUB2 program grub-mkrescue on the other hand lets xorriso create a
Protective MBR and a valid GPT with a partition entry which marks the
EFI System Partition.
Have a nice day :)
Thomas
