A google search turned up this: 

One can also look code for the GNU/Linux ISO-9660 filesystem driver.
I think the relevant portion is .../linux-*/fs/isofs/rock.c

Somewhere in there I saw a comment that indicated special care needs
to be take when one handles *both* Joliet and Rock Ridge
extensions. (One of them has to be handled first for some aspect.)

You didn't mention what OS. Probably not Solaris because most Solaris
users about the vold daemon that does its magic. On RedHat there is a
MagicDev package that I think handles the CD.

Gee, it's rare when anybody writes that.
