  5. This is the standard file system used on CD-ROMs. It was previously
  6. known as "High Sierra File System" and is called "hsfs" on other
  7. Unix systems. The so-called Rock-Ridge extensions which allow for
  8. long Unix filenames and symbolic links are also supported by this
  9. driver. If you have a CD-ROM drive and want to do more with it than
  10. just listen to audio CDs and watch its LEDs, say Y (and read
  11. <file:Documentation/filesystems/isofs.rst> and the CD-ROM-HOWTO,
  12. available from <http://www.tldp.org/docs.html#howto>), thereby
  13. enlarging your kernel by about 27 KB; otherwise say N.
  14. To compile this file system support as a module, choose M here: the
  15. module will be called isofs.

  21. Joliet is a Microsoft extension for the ISO 9660 CD-ROM file system
  22. which allows for long filenames in unicode format (unicode is the
  23. new 16 bit character code, successor to ASCII, which encodes the
  24. characters of almost all languages of the world; see
  25. <http://www.unicode.org/> for more information). Say Y here if you
  26. want to be able to read Joliet CD-ROMs under Linux.

  31. help
  32. This is a Linux-specific extension to RockRidge which lets you store
  33. data in compressed form on a CD-ROM and have it transparently
  34. decompressed when the CD-ROM is accessed. See
  35. <http://www.kernel.org/pub/linux/utils/fs/zisofs/> for the tools
  36. necessary to create such a filesystem. Say Y here if you want to be
  37. able to read such compressed CD-ROMs.
