8 tristate "Second extended fs support"
10 This is the de facto standard Linux file system (method to organize
11 files on a storage device) for hard disks.
13 You want to say Y here, unless you intend to use Linux exclusively
14 from inside a DOS partition using the UMSDOS file system. The
15 advantage of the latter is that you can get away without
16 repartitioning your hard drive (which often implies backing
17 everything up and restoring afterwards); the disadvantage is that
18 Linux becomes susceptible to DOS viruses and that UMSDOS is somewhat
19 slower than ext2fs. Even if you want to run Linux in this fashion,
20 it might be a good idea to have ext2fs around: it enables you to
21 read more floppy disks and facilitates the transition to a *real*
22 Linux partition later. Another (rare) case which doesn't require
23 ext2fs is a diskless Linux box which mounts all files over the
24 network using NFS (in this case it's sufficient to say Y to "NFS
25 file system support" below). Saying Y here will enlarge your kernel
28 The Ext2fs-Undeletion mini-HOWTO, available from
29 <http://www.tldp.org/docs.html#howto>, gives information about
30 how to retrieve deleted files on ext2fs file systems.
32 To change the behavior of ext2 file systems, you can use the tune2fs
33 utility ("man tune2fs"). To modify attributes of files and
34 directories on ext2 file systems, use chattr ("man chattr").
36 Ext2fs partitions can be read from within DOS using the ext2tool
37 command line tool package (available from
38 <ftp://ibiblio.org/pub/Linux/system/filesystems/ext2/>) and from
39 within Windows NT using the ext2nt command line tool package from
40 <ftp://ibiblio.org/pub/Linux/utils/dos/>. Explore2fs is a
41 graphical explorer for ext2fs partitions which runs on Windows 95
42 and Windows NT and includes experimental write support; it is
44 <http://jnewbigin-pc.it.swin.edu.au/Linux/Explore2fs.htm>.
46 To compile this file system support as a module, choose M here: the
47 module will be called ext2. Be aware however that the file system
48 of your root partition (the one containing the directory /) cannot
49 be compiled as a module, and so this could be dangerous. Most
50 everyone wants to say Y here.
53 bool "Ext2 extended attributes"
56 Extended attributes are name:value pairs associated with inodes by
57 the kernel or by users (see the attr(5) manual page, or visit
58 <http://acl.bestbits.at/> for details).
62 config EXT2_FS_POSIX_ACL
63 bool "Ext2 POSIX Access Control Lists"
64 depends on EXT2_FS_XATTR
66 Posix Access Control Lists (ACLs) support permissions for users and
67 groups beyond the owner/group/world scheme.
69 To learn more about Access Control Lists, visit the Posix ACLs for
70 Linux website <http://acl.bestbits.at/>.
72 If you don't know what Access Control Lists are, say N
74 config EXT2_FS_SECURITY
75 bool "Ext2 Security Labels"
76 depends on EXT2_FS_XATTR
78 Security labels support alternative access control models
79 implemented by security modules like SELinux. This option
80 enables an extended attribute handler for file security
81 labels in the ext2 filesystem.
83 If you are not using a security module that requires using
84 extended attributes for file security labels, say N.
87 tristate "Ext3 journalling file system support"
89 This is the journaling version of the Second extended file system
90 (often called ext3), the de facto standard Linux file system
91 (method to organize files on a storage device) for hard disks.
93 The journaling code included in this driver means you do not have
94 to run e2fsck (file system checker) on your file systems after a
95 crash. The journal keeps track of any changes that were being made
96 at the time the system crashed, and can ensure that your file system
97 is consistent without the need for a lengthy check.
99 Other than adding the journal to the file system, the on-disk format
100 of ext3 is identical to ext2. It is possible to freely switch
101 between using the ext3 driver and the ext2 driver, as long as the
102 file system has been cleanly unmounted, or e2fsck is run on the file
105 To add a journal on an existing ext2 file system or change the
106 behavior of ext3 file systems, you can use the tune2fs utility ("man
107 tune2fs"). To modify attributes of files and directories on ext3
108 file systems, use chattr ("man chattr"). You need to be using
109 e2fsprogs version 1.20 or later in order to create ext3 journals
110 (available at <http://sourceforge.net/projects/e2fsprogs/>).
112 To compile this file system support as a module, choose M here: the
113 module will be called ext3. Be aware however that the file system
114 of your root partition (the one containing the directory /) cannot
115 be compiled as a module, and so this may be dangerous.
118 bool "Ext3 extended attributes"
122 Extended attributes are name:value pairs associated with inodes by
123 the kernel or by users (see the attr(5) manual page, or visit
124 <http://acl.bestbits.at/> for details).
128 You need this for POSIX ACL support on ext3.
130 config EXT3_FS_POSIX_ACL
131 bool "Ext3 POSIX Access Control Lists"
132 depends on EXT3_FS_XATTR
134 Posix Access Control Lists (ACLs) support permissions for users and
135 groups beyond the owner/group/world scheme.
137 To learn more about Access Control Lists, visit the Posix ACLs for
138 Linux website <http://acl.bestbits.at/>.
140 If you don't know what Access Control Lists are, say N
142 config EXT3_FS_SECURITY
143 bool "Ext3 Security Labels"
144 depends on EXT3_FS_XATTR
146 Security labels support alternative access control models
147 implemented by security modules like SELinux. This option
148 enables an extended attribute handler for file security
149 labels in the ext3 filesystem.
151 If you are not using a security module that requires using
152 extended attributes for file security labels, say N.
155 # CONFIG_JBD could be its own option (even modular), but until there are
156 # other users than ext3, we will simply make it be the same as CONFIG_EXT3_FS
157 # dep_tristate ' Journal Block Device support (JBD for ext3)' CONFIG_JBD $CONFIG_EXT3_FS
161 This is a generic journaling layer for block devices. It is
162 currently used by the ext3 file system, but it could also be used to
163 add journal support to other file systems or block devices such as
166 If you are using the ext3 file system, you need to say Y here. If
167 you are not using ext3 then you will probably want to say N.
169 To compile this device as a module, choose M here: the module will be
170 called jbd. If you are compiling ext3 into the kernel, you cannot
171 compile this code as a module.
174 bool "JBD (ext3) debugging support"
177 If you are using the ext3 journaled file system (or potentially any
178 other file system/device using JBD), this option allows you to
179 enable debugging output while the system is running, in order to
180 help track down any problems you are having. By default the
181 debugging output will be turned off.
183 If you select Y here, then you will be able to turn on debugging
184 with "echo N > /proc/sys/fs/jbd-debug", where N is a number between
185 1 and 5, the higher the number, the more debugging output is
186 generated. To turn debugging off again, do
187 "echo 0 > /proc/sys/fs/jbd-debug".
190 # Meta block cache for Extended Attributes (ext2/ext3)
192 depends on EXT2_FS_XATTR || EXT3_FS_XATTR
193 default y if EXT2_FS=y || EXT3_FS=y
194 default m if EXT2_FS=m || EXT3_FS=m
197 tristate "Reiserfs support"
199 Stores not just filenames but the files themselves in a balanced
200 tree. Uses journaling.
202 Balanced trees are more efficient than traditional file system
203 architectural foundations.
205 In general, ReiserFS is as fast as ext2, but is very efficient with
206 large directories and small files. Additional patches are needed
207 for NFS and quotas, please see <http://www.namesys.com/> for links.
209 It is more easily extended to have features currently found in
210 database and keyword search systems than block allocation based file
211 systems are. The next version will be so extended, and will support
212 plugins consistent with our motto ``It takes more than a license to
213 make source code open.''
215 Read <http://www.namesys.com/> to learn more about reiserfs.
217 Sponsored by Threshold Networks, Emusic.com, and Bigstorage.com.
219 If you like it, you can pay us to add new features to it that you
220 need, buy a support contract, or pay us to port it to another OS.
222 config REISERFS_CHECK
223 bool "Enable reiserfs debug mode"
224 depends on REISERFS_FS
226 If you set this to Y, then ReiserFS will perform every check it can
227 possibly imagine of its internal consistency throughout its
228 operation. It will also go substantially slower. More than once we
229 have forgotten that this was on, and then gone despondent over the
230 latest benchmarks.:-) Use of this option allows our team to go all
231 out in checking for consistency when debugging without fear of its
232 effect on end users. If you are on the verge of sending in a bug
233 report, say Y and you might get a useful error message. Almost
234 everyone should say N.
236 config REISERFS_PROC_INFO
237 bool "Stats in /proc/fs/reiserfs"
238 depends on REISERFS_FS
240 Create under /proc/fs/reiserfs a hierarchy of files, displaying
241 various ReiserFS statistics and internal data at the expense of
242 making your kernel or module slightly larger (+8 KB). This also
243 increases the amount of kernel memory required for each mount.
244 Almost everyone but ReiserFS developers and people fine-tuning
245 reiserfs or tracing problems should say N.
248 tristate "JFS filesystem support"
251 This is a port of IBM's Journaled Filesystem . More information is
252 available in the file Documentation/filesystems/jfs.txt.
254 If you do not intend to use the JFS filesystem, say N.
257 bool "JFS POSIX Access Control Lists"
260 Posix Access Control Lists (ACLs) support permissions for users and
261 groups beyond the owner/group/world scheme.
263 To learn more about Access Control Lists, visit the Posix ACLs for
264 Linux website <http://acl.bestbits.at/>.
266 If you don't know what Access Control Lists are, say N
272 If you are experiencing any problems with the JFS filesystem, say
273 Y here. This will result in additional debugging messages to be
274 written to the system log. Under normal circumstances, this
275 results in very little overhead.
277 config JFS_STATISTICS
278 bool "JFS statistics"
281 Enabling this option will cause statistics from the JFS file system
282 to be made available to the user in the /proc/fs/jfs/ directory.
285 # Posix ACL utility routines (for now, only ext2/ext3/jfs)
287 # NOTE: you can implement Posix ACLs without these helpers (XFS does).
288 # Never use this symbol for ifdefs.
291 depends on EXT2_FS_POSIX_ACL || EXT3_FS_POSIX_ACL || JFS_POSIX_ACL
295 tristate "XFS filesystem support"
297 XFS is a high performance journaling filesystem which originated
298 on the SGI IRIX platform. It is completely multi-threaded, can
299 support large files and large filesystems, extended attributes,
300 variable block sizes, is extent based, and makes extensive use of
301 Btrees (directories, extents, free space) to aid both performance
304 Refer to the documentation at <http://oss.sgi.com/projects/xfs/>
305 for complete details. This implementation is on-disk compatible
306 with the IRIX version of XFS.
308 To compile this file system support as a module, choose M here: the
309 module will be called xfs. Be aware, however, that if the file
310 system of your root partition is compiled as a module, you'll need
311 to use an initial ramdisk (initrd) to boot.
314 bool "Realtime support (EXPERIMENTAL)"
315 depends on XFS_FS && EXPERIMENTAL
317 If you say Y here you will be able to mount and use XFS filesystems
318 which contain a realtime subvolume. The realtime subvolume is a
319 separate area of disk space where only file data is stored. The
320 realtime subvolume is designed to provide very deterministic
321 data rates suitable for media streaming applications.
323 See the xfs man page in section 5 for a bit more information.
325 This feature is unsupported at this time, is not yet fully
326 functional, and may cause serious problems.
334 If you say Y here, you will be able to set limits for disk usage on
335 a per user and/or a per group basis under XFS. XFS considers quota
336 information as filesystem metadata and uses journaling to provide a
337 higher level guarantee of consistency. The on-disk data format for
338 quota is also compatible with the IRIX version of XFS, allowing a
339 filesystem to be migrated between Linux and IRIX without any need
342 If unsure, say N. More comprehensive documentation can be found in
343 README.quota in the xfsprogs package. XFS quota can be used either
344 with or without the generic quota support enabled (CONFIG_QUOTA) -
345 they are completely independent subsystems.
348 bool "Security Label support"
351 Security labels support alternative access control models
352 implemented by security modules like SELinux. This option
353 enables an extended attribute namespace for inode security
354 labels in the XFS filesystem.
356 If you are not using a security module that requires using
357 extended attributes for inode security labels, say N.
360 bool "POSIX ACL support"
363 POSIX Access Control Lists (ACLs) support permissions for users and
364 groups beyond the owner/group/world scheme.
366 To learn more about Access Control Lists, visit the POSIX ACLs for
367 Linux website <http://acl.bestbits.at/>.
369 If you don't know what Access Control Lists are, say N.
372 tristate "Minix fs support"
374 Minix is a simple operating system used in many classes about OS's.
375 The minix file system (method to organize files on a hard disk
376 partition or a floppy disk) was the original file system for Linux,
377 but has been superseded by the second extended file system ext2fs.
378 You don't want to use the minix file system on your hard disk
379 because of certain built-in restrictions, but it is sometimes found
380 on older Linux floppy disks. This option will enlarge your kernel
381 by about 28 KB. If unsure, say N.
383 To compile this file system support as a module, choose M here: the
384 module will be called minix. Note that the file system of your root
385 partition (the one containing the directory /) cannot be compiled as
389 tristate "ROM file system support"
391 This is a very small read-only file system mainly intended for
392 initial ram disks of installation disks, but it could be used for
393 other read-only media as well. Read
394 <file:Documentation/filesystems/romfs.txt> for details.
396 To compile this file system support as a module, choose M here: the
397 module will be called romfs. Note that the file system of your
398 root partition (the one containing the directory /) cannot be a
401 If you don't know whether you need it, then you don't need it:
407 If you say Y here, you will be able to set per user limits for disk
408 usage (also called disk quotas). Currently, it works for the
409 ext2, ext3, and reiserfs file system. You need additional software
410 in order to use quota support (you can download sources from
411 <http://www.sf.net/projects/linuxquota/>). For further details, read
412 the Quota mini-HOWTO, available from
413 <http://www.tldp.org/docs.html#howto>. Probably the quota
414 support is only useful for multi user systems. If unsure, say N.
417 tristate "Old quota format support"
420 This quota format was (is) used by kernels earlier than 2.4.??. If
421 you have quota working and you don't want to convert to new quota
425 tristate "Quota format v2 support"
428 This quota format allows using quotas with 32-bit UIDs/GIDs. If you
429 need this functionality say Y here. Note that you will need latest
430 quota utilities for new quota format with this kernel.
434 depends on XFS_QUOTA || QUOTA
438 tristate "Kernel automounter support"
440 The automounter is a tool to automatically mount remote file systems
441 on demand. This implementation is partially kernel-based to reduce
442 overhead in the already-mounted case; this is unlike the BSD
443 automounter (amd), which is a pure user space daemon.
445 To use the automounter you need the user-space tools from the autofs
446 package; you can find the location in <file:Documentation/Changes>.
447 You also want to answer Y to "NFS file system support", below.
449 If you want to use the newer version of the automounter with more
450 features, say N here and say Y to "Kernel automounter v4 support",
453 To compile this support as a module, choose M here: the module will be
456 If you are not a part of a fairly large, distributed network, you
457 probably do not need an automounter, and can say N here.
460 tristate "Kernel automounter version 4 support (also supports v3)"
462 The automounter is a tool to automatically mount remote file systems
463 on demand. This implementation is partially kernel-based to reduce
464 overhead in the already-mounted case; this is unlike the BSD
465 automounter (amd), which is a pure user space daemon.
467 To use the automounter you need the user-space tools from
468 <ftp://ftp.kernel.org/pub/linux/daemons/autofs/testing-v4/>; you also
469 want to answer Y to "NFS file system support", below.
471 To compile this support as a module, choose M here: the module will be
472 called autofs4. You will need to add "alias autofs autofs4" to your
473 modules configuration file.
475 If you are not a part of a fairly large, distributed network or
476 don't have a laptop which needs to dynamically reconfigure to the
477 local network, you probably do not need an automounter, and can say
480 menu "CD-ROM/DVD Filesystems"
483 tristate "ISO 9660 CDROM file system support"
485 This is the standard file system used on CD-ROMs. It was previously
486 known as "High Sierra File System" and is called "hsfs" on other
487 Unix systems. The so-called Rock-Ridge extensions which allow for
488 long Unix filenames and symbolic links are also supported by this
489 driver. If you have a CD-ROM drive and want to do more with it than
490 just listen to audio CDs and watch its LEDs, say Y (and read
491 <file:Documentation/filesystems/isofs.txt> and the CD-ROM-HOWTO,
492 available from <http://www.tldp.org/docs.html#howto>), thereby
493 enlarging your kernel by about 27 KB; otherwise say N.
495 To compile this file system support as a module, choose M here: the
496 module will be called isofs.
499 bool "Microsoft Joliet CDROM extensions"
500 depends on ISO9660_FS
503 Joliet is a Microsoft extension for the ISO 9660 CD-ROM file system
504 which allows for long filenames in unicode format (unicode is the
505 new 16 bit character code, successor to ASCII, which encodes the
506 characters of almost all languages of the world; see
507 <http://www.unicode.org/> for more information). Say Y here if you
508 want to be able to read Joliet CD-ROMs under Linux.
511 bool "Transparent decompression extension"
512 depends on ISO9660_FS
515 This is a Linux-specific extension to RockRidge which lets you store
516 data in compressed form on a CD-ROM and have it transparently
517 decompressed when the CD-ROM is accessed. See
518 <http://www.kernel.org/pub/linux/utils/fs/zisofs/> for the tools
519 necessary to create such a filesystem. Say Y here if you want to be
520 able to read such compressed CD-ROMs.
523 # for fs/nls/Config.in
529 tristate "UDF file system support"
531 This is the new file system used on some CD-ROMs and DVDs. Say Y if
532 you intend to mount DVD discs or CDRW's written in packet mode, or
533 if written to by other UDF utilities, such as DirectCD.
534 Please read <file:Documentation/filesystems/udf.txt>.
536 To compile this file system support as a module, choose M here: the
537 module will be called udf.
543 menu "DOS/FAT/NT Filesystems"
546 tristate "DOS FAT fs support"
549 If you want to use one of the FAT-based file systems (the MS-DOS,
550 VFAT (Windows 95) and UMSDOS (used to run Linux on top of an
551 ordinary DOS partition) file systems), then you must say Y or M here
552 to include FAT support. You will then be able to mount partitions or
553 diskettes with FAT-based file systems and transparently access the
554 files on them, i.e. MSDOS files will look and behave just like all
557 This FAT support is not a file system in itself, it only provides
558 the foundation for the other file systems. You will have to say Y or
559 M to at least one of "MSDOS fs support" or "VFAT fs support" in
560 order to make use of it.
562 Another way to read and write MSDOS floppies and hard drive
563 partitions from within Linux (but not transparently) is with the
564 mtools ("man mtools") program suite. You don't need to say Y here in
567 If you need to move large files on floppies between a DOS and a
568 Linux box, say Y here, mount the floppy under Linux with an MSDOS
569 file system and use GNU tar's M option. GNU tar is a program
570 available for Unix and DOS ("man tar" or "info tar").
572 It is now also becoming possible to read and write compressed FAT
573 file systems; read <file:Documentation/filesystems/fat_cvf.txt> for
576 The FAT support will enlarge your kernel by about 37 KB. If unsure,
579 To compile this as a module, choose M here: the module will be called
580 fat. Note that if you compile the FAT support as a module, you
581 cannot compile any of the FAT-based file systems into the kernel
582 -- they will have to be modules as well.
583 The file system of your root partition (the one containing the
584 directory /) cannot be a module, so don't say M here if you intend
585 to use UMSDOS as your root file system.
588 tristate "MSDOS fs support"
591 This allows you to mount MSDOS partitions of your hard drive (unless
592 they are compressed; to access compressed MSDOS partitions under
593 Linux, you can either use the DOS emulator DOSEMU, described in the
594 DOSEMU-HOWTO, available from
595 <http://www.tldp.org/docs.html#howto>, or try dmsdosfs in
596 <ftp://ibiblio.org/pub/Linux/system/filesystems/dosfs/>. If you
597 intend to use dosemu with a non-compressed MSDOS partition, say Y
598 here) and MSDOS floppies. This means that file access becomes
599 transparent, i.e. the MSDOS files look and behave just like all
602 If you want to use UMSDOS, the Unix-like file system on top of a
603 DOS file system, which allows you to run Linux from within a DOS
604 partition without repartitioning, you'll have to say Y or M here.
606 If you have Windows 95 or Windows NT installed on your MSDOS
607 partitions, you should use the VFAT file system (say Y to "VFAT fs
608 support" below), or you will not be able to see the long filenames
609 generated by Windows 95 / Windows NT.
611 This option will enlarge your kernel by about 7 KB. If unsure,
612 answer Y. This will only work if you said Y to "DOS FAT fs support"
613 as well. To compile this as a module, choose M here: the module will
617 tristate "VFAT (Windows-95) fs support"
620 This option provides support for normal Windows file systems with
621 long filenames. That includes non-compressed FAT-based file systems
622 used by Windows 95, Windows 98, Windows NT 4.0, and the Unix
623 programs from the mtools package.
625 You cannot use the VFAT file system for your Linux root partition
626 (the one containing the directory /); use UMSDOS instead if you
627 want to run Linux from within a DOS partition (i.e. say Y to
628 "Unix like fs on top of std MSDOS fs", below).
630 The VFAT support enlarges your kernel by about 10 KB and it only
631 works if you said Y to the "DOS FAT fs support" above. Please read
632 the file <file:Documentation/filesystems/vfat.txt> for details. If
635 To compile this as a module, choose M here: the module will be called
639 #dep_tristate ' UMSDOS: Unix-like file system on top of standard MSDOS fs' CONFIG_UMSDOS_FS $CONFIG_MSDOS_FS
640 # UMSDOS is temprory broken
643 Say Y here if you want to run Linux from within an existing DOS
644 partition of your hard drive. The advantage of this is that you can
645 get away without repartitioning your hard drive (which often implies
646 backing everything up and restoring afterwards) and hence you're
647 able to quickly try out Linux or show it to your friends; the
648 disadvantage is that Linux becomes susceptible to DOS viruses and
649 that UMSDOS is somewhat slower than ext2fs. Another use of UMSDOS
650 is to write files with long unix filenames to MSDOS floppies; it
651 also allows Unix-style soft-links and owner/permissions of files on
652 MSDOS floppies. You will need a program called umssync in order to
653 make use of UMSDOS; read
654 <file:Documentation/filesystems/umsdos.txt>.
656 To get utilities for initializing/checking UMSDOS file system, or
657 latest patches and/or information, visit the UMSDOS home page at
658 <http://www.voyager.hr/~mnalis/umsdos/>.
660 This option enlarges your kernel by about 28 KB and it only works if
661 you said Y to both "DOS FAT fs support" and "MSDOS fs support"
662 above. To compile this as a module, choose M here: the module will be
663 called umsdos. Note that the file system of your root partition
664 (the one containing the directory /) cannot be a module, so saying M
665 could be dangerous. If unsure, say N.
668 tristate "NTFS file system support"
671 NTFS is the file system of Microsoft Windows NT, 2000, XP and 2003.
673 Saying Y or M here enables read support. There is partial, but
674 safe, write support available. For write support you must also
675 say Y to "NTFS write support" below.
677 There are also a number of user-space tools available, called
678 ntfsprogs. These include ntfsundelete and ntfsresize, that work
679 without NTFS support enabled in the kernel.
681 This is a rewrite from scratch of Linux NTFS support and replaced
682 the old NTFS code starting with Linux 2.5.11. A backport to
683 the Linux 2.4 kernel series is separately available as a patch
684 from the project web site.
686 For more information see <file:Documentation/filesystems/ntfs.txt>
687 and <http://linux-ntfs.sourceforge.net/>.
689 To compile this file system support as a module, choose M here: the
690 module will be called ntfs.
692 If you are not using Windows NT, 2000, XP or 2003 in addition to
693 Linux on your computer it is safe to say N.
696 bool "NTFS debugging support"
699 If you are experiencing any problems with the NTFS file system, say
700 Y here. This will result in additional consistency checks to be
701 performed by the driver as well as additional debugging messages to
702 be written to the system log. Note that debugging messages are
703 disabled by default. To enable them, supply the option debug_msgs=1
704 at the kernel command line when booting the kernel or as an option
705 to insmod when loading the ntfs module. Once the driver is active,
706 you can enable debugging messages by doing (as root):
707 echo 1 > /proc/sys/fs/ntfs-debug
708 Replacing the "1" with "0" would disable debug messages.
710 If you leave debugging messages disabled, this results in little
711 overhead, but enabling debug messages results in very significant
712 slowdown of the system.
714 When reporting bugs, please try to have available a full dump of
715 debugging messages while the misbehaviour was occurring.
718 bool "NTFS write support"
721 This enables the partial, but safe, write support in the NTFS driver.
723 The only supported operation is overwriting existing files, without
724 changing the file length. No file or directory creation, deletion or
725 renaming is possible. Note only non-resident files can be written to
726 so you may find that some very small files (<500 bytes or so) cannot
729 While we cannot guarantee that it will not damage any data, we have
730 so far not received a single report where the driver would have
731 damaged someones data so we assume it is perfectly safe to use.
733 Note: While write support is safe in this version (a rewrite from
734 scratch of the NTFS support), it should be noted that the old NTFS
735 write support, included in Linux 2.5.10 and before (since 1997),
738 This is currently useful with TopologiLinux. TopologiLinux is run
739 on top of any DOS/Microsoft Windows system without partitioning your
740 hard disk. Unlike other Linux distributions TopologiLinux does not
741 need its own partition. For more information see
742 <http://topologi-linux.sourceforge.net/>
744 It is perfectly safe to say N here.
748 menu "Pseudo filesystems"
751 bool "/proc file system support"
753 This is a virtual file system providing information about the status
754 of the system. "Virtual" means that it doesn't take up any space on
755 your hard disk: the files are created on the fly by the kernel when
756 you try to access them. Also, you cannot read the files with older
757 version of the program less: you need to use more or cat.
759 It's totally cool; for example, "cat /proc/interrupts" gives
760 information about what the different IRQs are used for at the moment
761 (there is a small number of Interrupt ReQuest lines in your computer
762 that are used by the attached devices to gain the CPU's attention --
763 often a source of trouble if two devices are mistakenly configured
764 to use the same IRQ). The program procinfo to display some
765 information about your system gathered from the /proc file system.
767 Before you can use the /proc file system, it has to be mounted,
768 meaning it has to be given a location in the directory hierarchy.
769 That location should be /proc. A command such as "mount -t proc proc
770 /proc" or the equivalent line in /etc/fstab does the job.
772 The /proc file system is explained in the file
773 <file:Documentation/filesystems/proc.txt> and on the proc(5) manpage
776 This option will enlarge your kernel by about 67 KB. Several
777 programs depend on this, so everyone should say Y here.
784 bool "/dev file system support (OBSOLETE)"
785 depends on EXPERIMENTAL
787 This is support for devfs, a virtual file system (like /proc) which
788 provides the file system interface to device drivers, normally found
789 in /dev. Devfs does not depend on major and minor number
790 allocations. Device drivers register entries in /dev which then
791 appear automatically, which means that the system administrator does
792 not have to create character and block special device files in the
793 /dev directory using the mknod command (or MAKEDEV script) anymore.
795 This is work in progress. If you want to use this, you *must* read
796 the material in <file:Documentation/filesystems/devfs/>, especially
797 the file README there.
799 Note that devfs no longer manages /dev/pts! If you are using UNIX98
800 ptys, you will also need to mount the /dev/pts filesystem (devpts).
802 Note that devfs has been obsoleted by udev,
803 <http://www.kernel.org/pub/linux/utils/kernel/hotplug/>.
804 It has been stripped down to a bare minimum and is only provided for
805 legacy installations that use its naming scheme which is
806 unfortunately different from the names normal Linux installations
812 bool "Automatically mount at boot"
815 This option appears if you have CONFIG_DEVFS_FS enabled. Setting
816 this to 'Y' will make the kernel automatically mount devfs onto /dev
817 when the system is booted, before the init thread is started.
818 You can override this with the "devfs=nomount" boot option.
826 If you say Y here, then the /dev file system code will generate
827 debugging messages. See the file

844 bool "/dev/pts Security Labels"
845 depends on DEVPTS_FS_XATTR
847 Security labels support alternative access control models
848 implemented by security modules like SELinux. This option
849 enables an extended attribute handler for file security

858 Tmpfs is a file system which keeps all files in virtual memory.

898 systems and the Acorn Archimedes range of machines. If you say Y
899 here, Linux will be able to read from ADFS partitions on hard drives
900 and from ADFS-formatted floppy discs. If you also want to be able to
901 write to those devices, say Y to "ADFS write support" below.

922 depends on EXPERIMENTAL
924 The Fast File System (FFS) is the common file system used on hard
925 disks by Amiga(tm) systems since AmigaOS Version 1.3 (34.20). Say Y
926 if you want to be able to read and write files from and to an Amiga
927 FFS partition on your hard drive. Amiga floppies however cannot be
928 read with this driver due to an incompatibility of the floppy
929 controller used in an Amiga and the standard floppy controller in

961 This file system is often called HFS+ and was introduced with
962 MacOS 8. It includes all Mac specific filesystem data such as

971 The BeOS File System (BeFS) is the native file system of Be, Inc's
972 BeOS. Notable features include support for arbitrary attributes
973 on files and directories, and database-like indices on selected
974 attributes. (Also note that this driver doesn't make those features
975 available at this time). It is a 64 bit filesystem, so it supports
976 extreemly large volumes and files.
978 If you use this filesystem, you should also say Y to at least one

997 Boot File System (BFS) is a file system used under SCO UnixWare to
998 allow the bootloader access to the kernel image and other important
999 files during the boot process. It is usually mounted under /stand
1000 and corresponds to the slice marked as "STAND" in the UnixWare
1001 partition. You should say Y if you want to read or write the files
1002 on your /stand slice from within Linux. You then also need to say Y
1003 to "UnixWare slices support", below. More information about the BFS

1075 testing and debugging, it's advisable to set it to one. This will
1076 enable a few assertions and will print debugging messages at the
1077 KERN_DEBUG loglevel, where they won't normally be visible. Level 2
1078 is unlikely to be useful - it enables extra debugging in certain
1079 areas which at one point needed debugging, but when the bugs were

1090 This enables the experimental support for NAND flash in JFFS2. NAND
1091 is a newer type of flash chip design than the traditional NOR flash,
1092 with higher density but a handful of characteristics which make it

1186 here would allow you to read from their floppies and hard disk
1189 If you have floppies or hard disk partitions like that, it is likely
1190 that they contain binaries from those other Unix systems; in order
1191 to run these binaries, you will want to install linux-abi which is a

1196 NOTE: that will work only for binaries from Intel-based systems;
1197 PDP ones will have to wait until somebody ports Linux to -11 ;-)
1199 If you only intend to mount files from some other Unix over the
1200 network using NFS, you don't need the System V file system support
1201 (but you need NFS file system support obviously).
1203 Note that this option is generally not needed for floppies, since a
1204 good portable way to transport files and directories between unixes
1205 (and even other operating systems) is given by the tar program ("man

1222 BSD and derivate versions of Unix (such as SunOS, FreeBSD, NetBSD,
1223 OpenBSD and NeXTstep) use a file system called UFS. Some System V
1224 Unixes can create and mount hard disk partitions and diskettes using
1225 this file system as well. Saying Y here will allow you to read from

1228 file <file:Documentation/filesystems/ufs.txt> for more information.
1230 The recently released UFS2 variant (used in FreeBSD 5.x) is
1231 READ-ONLY supported.
1233 If you only intend to mount files from some other Unix over the
1234 network using NFS, you don't need the UFS file system support (but
1235 you need NFS file system support obviously).
1237 Note that this option is generally not needed for floppies, since a
1238 good portable way to transport files and directories between unixes
1239 (and even other operating systems) is given by the tar program ("man
1240 tar" or preferably "info tar").
1242 When accessing NeXTstep files, you may need to convert them from the

1270 (using SLIP, PLIP, PPP or Ethernet) and want to mount files residing
1271 on that computer (the NFS server) using the Network File Sharing
1272 protocol, say Y. "Mounting files" means that the client can access
1273 the files with usual UNIX commands as if they were sitting on the
1274 client's hard disk. For this to work, the server must run the
1275 programs nfsd and mountd (but does not need to have NFS file system
1276 support enabled in its kernel). NFS is explained in the Network
1277 Administrator's Guide, available from
1278 <http://www.tldp.org/docs.html#guide>, on its man page: "man
1279 nfs", and in the NFS-HOWTO.
1281 A superior but less widely used alternative to NFS is provided by
1282 the Coda file system; see "Coda file system support" below.
1284 If you say Y here, you should have said Y to TCP/IP networking also.

1327 This option enables applications to perform uncached I/O on files
1328 in NFS file systems using the O_DIRECT open() flag. When O_DIRECT
1329 is set for a file, its data is not cached in the system's page
1330 cache. Data is moved to and from user-level application buffers
1331 directly. Unlike local disk-based file systems, NFS O_DIRECT has
1332 no alignment restrictions.
1334 Unless your program is designed to use O_DIRECT properly, you are
1335 much better off allowing the NFS client to manage data caching for
1336 you. Misusing O_DIRECT can cause poor server performance or network
1337 storms. This kernel build option defaults OFF to avoid exposing
1338 system administrators unwittingly to a potentially hazardous
1341 For more details on NFS O_DIRECT, see fs/nfs/direct.c.

1354 computers on your local network which support NFS can access certain
1355 directories on your box transparently, you have two options: you can
1356 use the self-contained user space program nfsd, in which case you
1357 should say N here, or you can say Y and use the kernel based NFS
1358 server. The advantage of the kernel based solution is that it is
1361 In either case, you will need support software; the respective
1362 locations are given in the file <file:Documentation/Changes> in the
1365 If you say Y here, you will get support for version 2 of the NFS
1366 protocol (NFSv2). If you also want NFSv3, say Y to the next question
1369 Please read the NFS-HOWTO, available from
1370 <http://www.tldp.org/docs.html#howto>.
1372 To compile the NFS server support as a module, choose M here: the
1373 module will be called nfsd. If unsure, say N.
1376 bool "Provide NFSv3 server support"
1379 If you would like to include the NFSv3 server as well as the NFSv2
1380 server, say Y here. If unsure, say Y.
1383 bool "Provide NFSv4 server support (EXPERIMENTAL)"
1384 depends on NFSD_V3 && EXPERIMENTAL
1386 If you would like to include the NFSv4 server as well as the NFSv2
1387 and NFSv3 servers, say Y here. This feature is experimental, and
1388 should only be used if you are interested in helping to test NFSv4.
1392 bool "Provide NFS server over TCP support (EXPERIMENTAL)"
1393 depends on NFSD && EXPERIMENTAL
1395 Enable NFS service over TCP connections. This the officially
1396 still experimental, but seems to work well.
1399 bool "Root file system on NFS"
1400 depends on NFS_FS=y && IP_PNP
1402 If you want your Linux box to mount its whole root file system (the
1403 one containing the directory /) from some other computer over the
1404 net via NFS (presumably because your box doesn't have a hard disk),
1405 say Y. Read <file:Documentation/nfsroot.txt> for details. It is
1406 likely that in this case, you also want to say Y to "Kernel level IP
1407 autoconfiguration" so that your box can discover its network address
1410 Most people say N here.
1417 depends on NFSD_V3 || NFS_V3
1430 config RPCSEC_GSS_KRB5
1431 tristate "Secure RPC: Kerberos V mechanism (EXPERIMENTAL)"
1432 depends on SUNRPC && EXPERIMENTAL
1438 Provides for secure RPC calls by means of a gss-api
1439 mechanism based on Kerberos V5. This is required for
1442 Note: Requires an auxiliary userspace daemon which may be found on
1443 http://www.citi.umich.edu/projects/nfsv4/
1448 tristate "SMB file system support (to mount Windows shares etc.)"
1452 SMB (Server Message Block) is the protocol Windows for Workgroups
1453 (WfW), Windows 95/98, Windows NT and OS/2 Lan Manager use to share
1454 files and printers over local networks. Saying Y here allows you to
1455 mount their file systems (often called "shares" in this context) and
1456 access them just like any other Unix directory. Currently, this
1457 works only if the Windows machines use TCP/IP as the underlying
1458 transport protocol, and not NetBEUI. For details, read
1459 <file:Documentation/filesystems/smbfs.txt> and the SMB-HOWTO,
1460 available from <http://www.tldp.org/docs.html#howto>.
1462 Note: if you just want your box to act as an SMB *server* and make
1463 files and printing services available to Windows clients (which need
1464 to have a TCP/IP stack), you don't need to say Y here; you can use
1465 the program SAMBA (available from <ftp://ftp.samba.org/pub/samba/>)
1468 General information about how to connect Linux, Windows machines and
1469 Macs is on the WWW at <http://www.eats.com/linux_mac_win.html>.
1471 To compile the SMB support as a module, choose M here: the module will
1472 be called smbfs. Most people say N, however.
1474 config SMB_NLS_DEFAULT
1475 bool "Use a default NLS"
1478 Enabling this will make smbfs use nls translations by default. You
1479 need to specify the local charset (CONFIG_NLS_DEFAULT) in the nls
1480 settings and you need to give the default nls for the SMB server as
1481 CONFIG_SMB_NLS_REMOTE.
1483 The nls settings can be changed at mount time, if your smbmount
1484 supports that, using the codepage and iocharset parameters.
1486 smbmount from samba 2.2.0 or later supports this.
1488 config SMB_NLS_REMOTE
1489 string "Default Remote NLS Option"
1490 depends on SMB_NLS_DEFAULT
1493 This setting allows you to specify a default value for which
1494 codepage the server uses. If this field is left blank no
1495 translations will be done by default. The local codepage/charset
1496 default to CONFIG_NLS_DEFAULT.
1498 The nls settings can be changed at mount time, if your smbmount
1499 supports that, using the codepage and iocharset parameters.
1501 smbmount from samba 2.2.0 or later supports this.
1504 tristate "CIFS support (advanced network filesystem for Samba, Window and other CIFS compliant servers)(EXPERIMENTAL)"
1508 This is the client VFS module for the Common Internet File System
1509 (CIFS) protocol which is the successor to the Server Message Block
1510 (SMB) protocol, the native file sharing mechanism for most early
1511 PC operating systems. CIFS is fully supported by current network
1512 file servers such as Windows 2000 (including Windows NT version 4
1513 and Windows XP) as well by Samba (which provides excellent CIFS
1514 server support for Linux and many other operating systems). For
1515 production systems the smbfs module may be used instead of this
1516 cifs module since smbfs is currently more stable and provides
1517 support for older servers. The intent of this module is to provide the
1518 most advanced network file system function for CIFS compliant servers,
1519 including support for dfs (hierarchical name space), secure per-user
1520 session establishment, safe distributed caching (oplock), optional
1521 packet signing, Unicode and other internationalization improvements, and
1522 optional Winbind (nsswitch) integration. This module is in an early
1523 development stage, so unless you are specifically interested in this
1524 filesystem, just say N.
1527 tristate "NCP file system support (to mount NetWare volumes)"
1528 depends on IPX!=n || INET
1530 NCP (NetWare Core Protocol) is a protocol that runs over IPX and is
1531 used by Novell NetWare clients to talk to file servers. It is to
1532 IPX what NFS is to TCP/IP, if that helps. Saying Y here allows you
1533 to mount NetWare file server volumes and to access them just like
1534 any other Unix directory. For details, please read the file
1535 <file:Documentation/filesystems/ncpfs.txt> in the kernel source and
1536 the IPX-HOWTO from <http://www.tldp.org/docs.html#howto>.
1538 You do not have to say Y here if you want your Linux box to act as a
1539 file *server* for Novell NetWare clients.
1541 General information about how to connect Linux, Windows machines and
1542 Macs is on the WWW at <http://www.eats.com/linux_mac_win.html>.
1544 To compile this as a module, choose M here: the module will be called
1545 ncpfs. Say N unless you are connected to a Novell network.
1547 source "fs/ncpfs/Kconfig"
1550 tristate "Coda file system support (advanced network fs)"
1553 Coda is an advanced network file system, similar to NFS in that it
1554 enables you to mount file systems of a remote server and access them
1555 with regular Unix commands as if they were sitting on your hard
1556 disk. Coda has several advantages over NFS: support for
1557 disconnected operation (e.g. for laptops), read/write server
1558 replication, security model for authentication and encryption,
1559 persistent client caches and write back caching.
1561 If you say Y here, your Linux box will be able to act as a Coda
1562 *client*. You will need user level code as well, both for the
1563 client and server. Servers are currently user level, i.e. they need
1564 no kernel support. Please read
1565 <file:Documentation/filesystems/coda.txt> and check out the Coda
1566 home page <http://www.coda.cs.cmu.edu/>.
1568 To compile the coda client support as a module, choose M here: the
1569 module will be called coda.
1571 config CODA_FS_OLD_API
1572 bool "Use 96-bit Coda file identifiers"
1575 A new kernel-userspace API had to be introduced for Coda v6.0
1576 to support larger 128-bit file identifiers as needed by the
1577 new realms implementation.
1579 However this new API is not backward compatible with older
1580 clients. If you really need to run the old Coda userspace
1581 cache manager then say Y.
1583 For most cases you probably want to say N.
1586 # Intermezzo broke when we added the expanded NGROUPS patches
1588 config INTERMEZZO_FS
1589 tristate "InterMezzo file system support (replicating fs) (EXPERIMENTAL)"
1590 depends on INET && EXPERIMENTAL
1592 InterMezzo is a networked file system with disconnected operation
1593 and kernel level write back caching. It is most often used for
1594 replicating potentially large trees or keeping laptop/desktop copies
1597 If you say Y or M your kernel or module will provide InterMezzo
1598 support. You will also need a file server daemon, which you can get
1599 from <http://www.inter-mezzo.org/>.
1602 # for fs/nls/Config.in
1603 tristate "Andrew File System support (AFS) (Experimental)"
1604 depends on INET && EXPERIMENTAL
1607 If you say Y here, you will get an experimental Andrew File System
1608 driver. It currently only supports unsecured read-only AFS access.
