In linux kernel since version 2.6.20 (release Date: 2007-02-04)  
This is the standard file system used on CD-ROMs. It was previously
known as "High Sierra File System" and is called "hsfs" on other
Unix systems. The so-called Rock-Ridge extensions which allow for
long Unix filenames and symbolic links are also supported by this
driver. If you have a CD-ROM drive and want to do more with it than
just listen to audio CDs and watch its LEDs, say Y (and read
<file:Documentation/filesystems/isofs.rst> and the CD-ROM-HOWTO,
available from <http://www.tldp.org/docs.html#howto>), thereby
enlarging your kernel by about 27 KB; otherwise say N.

To compile this file system support as a module, choose M here: the
module will be called isofs.
