Success by mistake is a classical pattern. :))
We will learn more when success vanishes righteously.

To be exacting: They can get a MBR partition table. In case of the
Fedora ISO its MBR partition 2 is the boot starting point for EFI when
the ISO is presented on USB stick.

Partitioning is not a special property of a storage device, but rather
just a few blocks of data in a specified format. There are various
formats, of which MBR partition table probably stems from MS-DOS. The
modern successor is GUID Partition Table (GPT) as specified in UEFI.
Apple, BSD Unix, SUN, etc. have/had their own partition table formats.
Linux understands many of them and never introduced an own format, afaik.

Please Cc me in this case. I am only temporarily subscribed here while
waiting for Richard Shaw to get his paycheck and to make his decision
whether really to invest the hard-earned money in experiments with
BD-R multi-layer media.

(Further i subscribed to Tom Horsley's bug report about USB-DVD allergy.)

In general, questions about xorriso, cdrskin, libburn, libisofs, or
libisoburn may be posted to bug-xorriso@xxxxxxx .


Have a nice day :)
