- You're right. We're using "Rock Ridge." I'm surprised that "High
- Sierra" jumped out of my fingers when I was writing my post. We use
- the UNIX/Linux utility "mkisofs" to create the binary of the image and
- the option that we use is "-r" and "r" (and "R") in part stands for
- "Rock Ridge", so I should have known better.

- Thanks for the background. Sorry to have mislead people. "High
- Sierra" isn't even mentioned in the man page for mkisofs, so it really
- surprises me that I said this. Oh well, I guess I could have
- experienced worse surprises on the first day of April.
