OK, thanks.  The cdrecord "personality" is used to present a familiar 
legacy syntax? Can the same result be reached using xorriso with no 
personality?

OK.  The distinction between writing arbitrary data (stream, file, ?) and 
writing a file system hadn't crystalized well.  Software can take an 
action, or not, without direct evidence. To my thinking, all the examples 
in https://www.gnu.org/software/xorriso/ assume an ISO 9660 filesystem.  
No issue for an experienced user but a ready trap for a novice.

Thanks again,                       ... Peter E.
