The Rock Ridge Interchange Protocol (RRIP, IEEE P1282) is an extension to the ISO 9660 volume format which adds POSIX file system semantics.

The extension adds support for storing Unix-specific file information on ISO 9660 CD-ROMs. The availability of this information allows for better integration with a local Unix filesystem when a mount operation is performed (also see Mount point).

These extensions are, briefly:

  • Longer file names (up to 255 characters)
  • Fewer restrictions on characters allowed in filenames
  • UNIX-style file modes, user ids and group ids
  • Symbolic links
  • Deeper directory hierarchy

Facts

Rock Ridge is named after the fictional town from the movie Blazing Saddles.
