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. 15 16 To compile this file system support as a module, choose M here: the 17 module will be called isofs. 18 19config JOLIET 20 bool "Microsoft Joliet CDROM extensions" 21 depends on ISO9660_FS 22 select NLS 23 help 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. 30 31config ZISOFS 32 bool "Transparent decompression extension" 33 depends on ISO9660_FS 34 select ZLIB_INFLATE 35 help 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. 42
