- Stores not just filenames but the files themselves in a balanced

- Balanced trees are more efficient than traditional file system
- architectural foundations.
-
- In general, ReiserFS is as fast as ext2, but is very efficient with

- for NFS and quotas, please see <http://www.namesys.com/> for links.
-
- It is more easily extended to have features currently found in
- database and keyword search systems than block allocation based file
- systems are. The next version will be so extended, and will support
- plugins consistent with our motto ``It takes more than a license to
- make source code open.''

- Read <http://www.namesys.com/> to learn more about reiserfs.

- write support, included in Linux 2.5.10 and before (since 1997),

+ If you want to use one of the FAT-based file systems (the MS-DOS and

+ to include FAT support. You will then be able to mount partitions or
+ diskettes with FAT-based file systems and transparently access the

+ M to at least one of "MSDOS fs support" or "VFAT fs support" in
+ order to make use of it.
+
+ Another way to read and write MSDOS floppies and hard drive
+ partitions from within Linux (but not transparently) is with the
+ mtools ("man mtools") program suite. You don't need to say Y here in
+ order to do that.
+
+ If you need to move large files on floppies between a DOS and a
+ Linux box, say Y here, mount the floppy under Linux with an MSDOS
+ file system and use GNU tar's M option. GNU tar is a program
+ available for Unix and DOS ("man tar" or "info tar").
+
+ The FAT support will enlarge your kernel by about 37 KB. If unsure,

+
+ There are also a number of user-space tools available, called
+ ntfsprogs. These include ntfsundelete and ntfsresize, that work

+
+ This is a rewrite from scratch of Linux NTFS support and replaced
+ the old NTFS code starting with Linux 2.5.11. A backport to
+ the Linux 2.4 kernel series is separately available as a patch
+ from the project web site.
+
+ For more information see <file:Documentation/filesystems/ntfs.txt>

+ help
+ If you are experiencing any problems with the NTFS file system, say

+ be written to the system log. Note that debugging messages are
+ disabled by default. To enable them, supply the option debug_msgs=1
+ at the kernel command line when booting the kernel or as an option
+ to insmod when loading the ntfs module. Once the driver is active,
+ you can enable debugging messages by doing (as root):
+ echo 1 > /proc/sys/fs/ntfs-debug
+ Replacing the "1" with "0" would disable debug messages.
+
+ If you leave debugging messages disabled, this results in little
+ overhead, but enabling debug messages results in very significant

+
+ When reporting bugs, please try to have available a full dump of
+ debugging messages while the misbehaviour was occurring.

+ This enables the partial, but safe, write support in the NTFS driver.
+
+ The only supported operation is overwriting existing files, without
+ changing the file length. No file or directory creation, deletion or
+ renaming is possible. Note only non-resident files can be written to
+ so you may find that some very small files (<500 bytes or so) cannot
+ be written to.
+
+ While we cannot guarantee that it will not damage any data, we have
+ so far not received a single report where the driver would have
+ damaged someones data so we assume it is perfectly safe to use.
+
+ Note: While write support is safe in this version (a rewrite from
+ scratch of the NTFS support), it should be noted that the old NTFS
+ write support, included in Linux 2.5.10 and before (since 1997),
+ is not safe.
+

+ help
+ BSD and derivate versions of Unix (such as SunOS, FreeBSD, NetBSD,
+ OpenBSD and NeXTstep) use a file system called UFS. Some System V
+ Unixes can create and mount hard disk partitions and diskettes using
+ this file system as well. Saying Y here will allow you to read from
+ these partitions; if you also want to write to them, say Y to the
+ experimental "UFS file system write support", below. Please read the
+ file <file:Documentation/filesystems/ufs.txt> for more information.
+
+ The recently released UFS2 variant (used in FreeBSD 5.x) is
+ READ-ONLY supported.
+
+ Note that this option is generally not needed for floppies, since a
+ good portable way to transport files and directories between unixes
+ (and even other operating systems) is given by the tar program ("man
+ tar" or preferably "info tar").
+
+ When accessing NeXTstep files, you may need to convert them from the
+ NeXT character set to the Latin1 character set; use the program
+ recode ("info recode") for this purpose.
+
+ To compile the UFS file system support as a module, choose M here: the
+ module will be called ufs.
+
+ If you haven't heard about all of this before, it's safe to say N.
+
+config UFS_FS_WRITE
+ bool "UFS file system write support (DANGEROUS)"
+ depends on UFS_FS && EXPERIMENTAL
+ help
+ Say Y here if you want to try writing to UFS partitions. This is
+ experimental, so you should back up your UFS partitions beforehand.
+
+config UFS_DEBUG
+ bool "UFS debugging"
+ depends on UFS_FS
+ help
+ If you are experiencing any problems with the UFS filesystem, say
+ Y here. This will result in _many_ additional debugging messages to be
+ written to the system log.
