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 15 To compile this file system support as a module, choose M here: the 16 module will be called isofs. 17 18config JOLIET 19 bool "Microsoft Joliet CDROM extensions" 20 depends on ISO9660_FS 21 select NLS 22 help 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. 29 30config ZISOFS 31 bool "Transparent decompression extension" 32 depends on ISO9660_FS 33 select ZLIB_INFLATE 34 help 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.
