What are the Rock Ridge extensions?

The Rock Ridge extensions use some undefined fields in the ISO-9660 standard to allow full Unix-like filenames, symbolic links, and deep directories.

"Rock Ridge" is named after the town in the movie "Blazing Saddles" for no particular reason.

The latest revision of the RRIP/SUSP is 1.10; the draft version of these documents is available by e-mail from cdfsf@ymi.com or ftp at ftp.cdrom.com (/pub/rockridge/new).

Eric Youngdale has written a Gnu-ware ISO-9660+Rockridge formatter. It has been tested on both Linux and SunOS 4.1.3. You can ftp it from ftp.cdrom.com:/pub/cdrom/mkisofs-1.00.tar.gz.

Kodak's Build-It product, which is basically a system for authoring Portfolio Photo CDs, can also author non-Photo-CD ISO 9660 discs, with or without the Rock Ridge extensions. It runs on SunOS 4.1.3, and requires a SPARCStation 2 or SPARCStation 10 with at least 64 megs of RAM. It requires the Kodak PCD Writer 200, and a second SCSI port for the writer.

Information about Build-It can be obtained by anonymous FTP from the Kodak FTP server, ftp.kodak.com, in the directory photo-cd/portfolio.
