3 tristate "ISO 9660 CDROM file system support"
6 This is the standard file system used on CD-ROMs. It was previously
7 known as "High Sierra File System" and is called "hsfs" on other
8 Unix systems. The so-called Rock-Ridge extensions which allow for
9 long Unix filenames and symbolic links are also supported by this
10 driver. If you have a CD-ROM drive and want to do more with it than
11 just listen to audio CDs and watch its LEDs, say Y (and read
12 <file:Documentation/filesystems/isofs.rst> and the CD-ROM-HOWTO,
13 available from <http://www.tldp.org/docs.html#howto>), thereby
14 enlarging your kernel by about 27 KB; otherwise say N.
16 To compile this file system support as a module, choose M here: the
17 module will be called isofs.
20 bool "Microsoft Joliet CDROM extensions"
24 Joliet is a Microsoft extension for the ISO 9660 CD-ROM file system
25 which allows for long filenames in unicode format (unicode is the
26 new 16 bit character code, successor to ASCII, which encodes the
27 characters of almost all languages of the world; see
28 <http://www.unicode.org/> for more information). Say Y here if you
29 want to be able to read Joliet CD-ROMs under Linux.
32 bool "Transparent decompression extension"
36 This is a Linux-specific extension to RockRidge which lets you store
37 data in compressed form on a CD-ROM and have it transparently
38 decompressed when the CD-ROM is accessed. See
39 <http://www.kernel.org/pub/linux/utils/fs/zisofs/> for the tools
40 necessary to create such a filesystem. Say Y here if you want to be
41 able to read such compressed CD-ROMs.
