ISO 9660 CD-ROM file system support
CONFIG_ISO9660_FS
 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.txt> 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.
 
 If you want to compile this as a module ( = code which can be
 inserted in and removed from the running kernel whenever you want),
 say M here and read <file:Documentation/modules.txt>.  The module
 will be called isofs.o.
