Hi,
... still trying to make sense of the specs.

Do you mean that one has to interpret the statement of UEFI 2.4
"All EFI GUIDs (Globally Unique Identifiers) have the format described
in RFC 4122 [...]
It should also be noted that TimeLow, TimeMid, TimeHighAndVersion fields
in the EFI are encoded as little endian."
as
The text format of EFI GUIDs is the same as in RFC 4122, but the binary
representation is byte-swapped at the first 4, 2, and 2 bytes.
If so, then i have to change the interpretation of the text form with the
new xorriso option.
Have a nice day :)
