# SPDX-License-Identifier: GPL-2.0-only config [31mCONFIG_ISO9660_FS[0m tristate "ISO 9660 CDROM file system support" help This is the standard file system used on CD-ROMs. It was previously known as "High Sierra File System" and is called "hsfs" on other Unix systems. The so-called Rock-Ridge extensions which allow for long Unix filenames and symbolic links are also supported by this driver. If you have a CD-[31mCONFIG_ROM[0m drive and want to do more with it than just listen to audio CDs and watch its LEDs, say Y (and read <file:Documentation/filesystems/isofs.txt> and the CD-[31mCONFIG_ROM[0m-HOWTO, available from <http://www.tldp.org/docs.html#howto>), thereby enlarging your kernel by about 27 KB; otherwise say N. To compile this file system support as a module, choose [31mCONFIG_M[0m here: the module will be called isofs. config [31mCONFIG_JOLIET[0m bool "Microsoft Joliet CDROM extensions" depends on [31mCONFIG_ISO9660_FS[0m select [31mCONFIG_NLS[0m help Joliet is a Microsoft extension for the ISO 9660 CD-[31mCONFIG_ROM[0m file system which allows for long filenames in unicode format (unicode is the new 16 bit character code, successor to ASCII, which encodes the characters of almost all languages of the world; see <http://www.unicode.org/> for more information). Say Y here if you want to be able to read Joliet CD-ROMs under Linux. config [31mCONFIG_ZISOFS[0m bool "Transparent decompression extension" depends on [31mCONFIG_ISO9660_FS[0m select [31mCONFIG_ZLIB_INFLATE[0m help This is a Linux-specific extension to RockRidge which lets you store data in compressed form on a CD-[31mCONFIG_ROM[0m and have it transparently decompressed when the CD-[31mCONFIG_ROM[0m is accessed. See <http://www.kernel.org/pub/linux/utils/fs/zisofs/> for the tools necessary to create such a filesystem. Say Y here if you want to be able to read such compressed CD-ROMs. |
