Hi,

So my Sector Count unit of 512 bytes is ok
until other info emerges. (The Fedora wiki
gave me doubts.)
I am busily refactoring the xorriso level of
boot options. This will finally impose another
round of regression tests.
I'll give you a note when i am done with mine.

So i can join the behavior of mkisofs and
genisoimage that the sequence of -b and
-eltorito-alt-boot defines the sequence of
boot image entries in the boot catalog.
--efi-boot FILE will be documented as being
virtually enclosed in -eltorito-alt-boot options.
I.e.
-b ... boot.options \
--efi-boot FILE \
...
will be the same as
-b ... boot.options \
-eltorito-alt-boot \
--efi-boot FILE \
-eltorito-alt-boot \
...
No boot option like -boot-info-table will have a
chance to be attributed to --efi-boot.

I have implemented setting of ID String and
Selection Criteria in libisofs and in the own
command interface of xorriso.
So if we ever need it ... :)

I wrote to the author of that wiki article.
No answer yet.
Googling brought no insight either.
Any Fedora users here ?
What does mkisofs -help say ?
Have a nice day :)
