The so-called Rock-Ridge extensions which allow for 7*ddfaccd9SAlexey Dobriyan long Unix filenames and symbolic links are also supported by this 8*ddfaccd9SAlexey Dobriyan driver. If you have a CD-ROM drive and want to do more with it than 9*ddfaccd9SAlexey Dobriyan just listen to audio CDs and watch its LEDs, say Y (and read 10*ddfaccd9SAlexey Dobriyan <file:Documentation/filesystems/isofs.txt> and the CD-ROM-HOWTO, 11*ddfaccd9SAlexey Dobriyan available from <http://www.tldp.org/docs.html#howto>), thereby 12*ddfaccd9SAlexey Dobriyan enlarging your kernel by about 27 KB; otherwise say N. 13*ddfaccd9SAlexey Dobriyan 14*ddfaccd9SAlexey Dobriyan To compile this file system support as a module, choose M here: the 15*ddfaccd9SAlexey Dobriyan module will be called isofs. 16*ddfaccd9SAlexey Dobriyan 17*ddfaccd9SAlexey Dobriyanconfig JOLIET 18*ddfaccd9SAlexey Dobriyan bool "Microsoft Joliet CDROM extensions" 19*ddfaccd9SAlexey Dobriyan depends on ISO9660_FS 20*ddfaccd9SAlexey Dobriyan select NLS 21*ddfaccd9SAlexey Dobriyan help 22*ddfaccd9SAlexey Dobriyan Joliet is a Microsoft extension for the ISO 9660 CD-ROM file system 23*ddfaccd9SAlexey Dobriyan which allows for long filenames in unicode format (unicode is the 24*ddfaccd9SAlexey Dobriyan new 16 bit character code, successor to ASCII, which encodes the 25*ddfaccd9SAlexey Dobriyan characters of almost all languages of the world; see 26*ddfaccd9SAlexey Dobriyan <http://www.unicode.org/> for more information).
