"ISO 9660 CDROM file system support"
select BUFFER_HEAD
help
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.

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

"Transparent decompression extension"
depends on ISO9660_FS
select ZLIB_INFLATE
help
This is a Linux-specific extension to RockRidge which lets you store
data in compressed form on a CD-ROM
and have it transparently
decompressed when the CD-ROM is accessed. See
<
http://www.kernel.org/pub/linux/utils/fs/zisofs/> for the tools
necessary to create such a filesystem. Say Y here
if you want to be
able to read such compressed CD-ROMs.
