Rock Ridge is an extension to ISO9660. This means that it is still a valid ISO9660 disc that can be read on any DOS system. This is because there are actually two filenames for every file on a Rock Ridge disk - an ISO9660 8.3 name and the Rock Ridge name. DOS will use the 8.3 name, as will any other system that does not use the Rock Ridge extensions. Linux, SunOS and any other system that do understand Rock Ridge will use the Rock Ridge name. The linux filesystem even has an option that lets you tell it to ignore the Rock Ridge extensions, and if you use this you get the 8.3 names. I think it would be a serious mistake to make a 386bsd/linux disk without Rock Ridge. -Eric
