By golly, you're right I am. What you are saying (that I didn't
understand the first time I read it) was that using this syntax, you
don't actually need to give it an ISO file, any old file will do.

To me, that wasn't clear from the man page. I assumed that it actually
required an ISO file and wouldn't work without one. So, I never tried
it without one.

Yes, that is what the man page says.
So, I guess we can stop arguing now and agree to agree. B^)
