You are right. The problem is already in the branch "pbatard-multiextent2".
So i only adopted it when i started my git branch "pragmatic-multiextent"
from that branch. From then on i was a good foster parent until you
developed the changeset which finally got into the main branch:

  
https://git.savannah.gnu.org/cgit/libcdio.git/commit/?id=d758fa2253cca062e92ad0754a64c15a854db4ff
  https://lists.gnu.org/archive/html/libcdio-devel/2020-05/msg00017.html

(Reason for my involvement was national penance after FIFA World Cup 2018.)

Wouldn't help if Gentoo hadn't thought of it, because they are still using
mkisofs.

xorriso (1.5.5 in git) now has the proposed warning messages:

  xorriso : WARNING : EFI boot equipment is provided but no directory /EFI/BOOT
  xorriso : WARNING : will emerge in the ISO filesystem. A popular method to
  xorriso : WARNING : prepare a USB stick on MS-Windows relies on having in the
  xorriso : WARNING : ISO filesystem a copy of the EFI system partition tree.

My offer stands to add another warning line with the URL of a document
which describes the needs of the unpacking method(s).
I would also be willing to adopt such a description for the docs of libisofs
and GNU xorriso, if your license permits it.

These and any other constraints should be documented in a quick-to-read
manner.
(Consider to write a very concise checklist section and to give detailed
motivation in further parts of the document. As i know my distro users
they have about 5 minutes time per month for this aspect of their work.)


Have a nice day :)
