ddfaccd995b2d (Alexey Dobriyan 2009-01-22 10:35:21 +0300 5) This is the standard file system used on CD-ROMs. It was previously
ddfaccd995b2d (Alexey Dobriyan 2009-01-22 10:35:21 +0300 6) known as "High Sierra File System" and is called "hsfs" on other
ddfaccd995b2d (Alexey Dobriyan 2009-01-22 10:35:21 +0300 7) Unix systems. The so-called Rock-Ridge extensions which allow for
ddfaccd995b2d (Alexey Dobriyan 2009-01-22 10:35:21 +0300 8) long Unix filenames and symbolic links are also supported by this
ddfaccd995b2d (Alexey Dobriyan 2009-01-22 10:35:21 +0300 9) driver. If you have a CD-ROM drive and want to do more with it than
