3 tristate "ISO 9660 CDROM file system support"
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.
15 To compile this file system support as a module, choose M here: the
16 module will be called isofs.
19 bool "Microsoft Joliet CDROM extensions"
23 Joliet is a Microsoft extension for the ISO 9660 CD-ROM file system
24 which allows for long filenames in unicode format (unicode is the
25 new 16 bit character code, successor to ASCII, which encodes the
26 characters of almost all languages of the world; see
27 <http://www.unicode.org/> for more information). Say Y here if you
28 want to be able to read Joliet CD-ROMs under Linux.
31 bool "Transparent decompression extension"
35 This is a Linux-specific extension to RockRidge which lets you store
36 data in compressed form on a CD-ROM and have it transparently
37 decompressed when the CD-ROM is accessed. See
38 <http://www.kernel.org/pub/linux/utils/fs/zisofs/> for the tools
39 necessary to create such a filesystem. Say Y here if you want to be
40 able to read such compressed CD-ROMs.
