-          Balanced trees are more efficient than traditional file system
-          architectural foundations.
-
-          In general, ReiserFS is as fast as ext2, but is very efficient with
-          large directories and small files.  Additional patches are needed
-          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.''

+        help
+          Coda is an advanced network file system, similar to NFS in that it
+          enables you to mount file systems of a remote server and access them
+          with regular Unix commands as if they were sitting on your hard
+          disk.  Coda has several advantages over NFS: support for
+          disconnected operation (e.g. for laptops), read/write server
+          replication, security model for authentication and encryption,
+          persistent client caches and write back caching.
+
+          If you say Y here, your Linux box will be able to act as a Coda
+          *client*.  You will need user level code as well, both for the
+          client and server.  Servers are currently user level, i.e. they need
+          no kernel support.  Please read
+          <file:Documentation/filesystems/coda.txt> and check out the Coda
+          home page <http://www.coda.cs.cmu.edu/>.
+
+          To compile the coda client support as a module, choose M here: the
+          module will be called coda.

+config FAT_FS
+        tristate
+        select NLS
+        help
+          If you want to use one of the FAT-based file systems (the MS-DOS and
+          VFAT (Windows 95) file systems), then you must say Y or M here
+          to include FAT support. You will then be able to mount partitions or
+          diskettes with FAT-based file systems and transparently access the
+          files on them, i.e. MSDOS files will look and behave just like all
+          other Unix files.
+
+          This FAT support is not a file system in itself, it only provides
+          the foundation for the other file systems. You will have to say Y or
+          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,
+          say Y.
+
+          To compile this as a module, choose M here: the module will be called
+          fat.  Note that if you compile the FAT support as a module, you
+          cannot compile any of the FAT-based file systems into the kernel
+          -- they will have to be modules as well.
+
+config MSDOS_FS
+        tristate "MSDOS fs support"
+        select FAT_FS
+        help
+          This allows you to mount MSDOS partitions of your hard drive (unless
+          they are compressed; to access compressed MSDOS partitions under
+          Linux, you can either use the DOS emulator DOSEMU, described in the
+          DOSEMU-HOWTO, available from
+          <http://www.tldp.org/docs.html#howto>, or try dmsdosfs in
+          <ftp://ibiblio.org/pub/Linux/system/filesystems/dosfs/>. If you
+          intend to use dosemu with a non-compressed MSDOS partition, say Y
+          here) and MSDOS floppies. This means that file access becomes
+          transparent, i.e. the MSDOS files look and behave just like all
+          other Unix files.
+
+          If you have Windows 95 or Windows NT installed on your MSDOS
+          partitions, you should use the VFAT file system (say Y to "VFAT fs
+          support" below), or you will not be able to see the long filenames
+          generated by Windows 95 / Windows NT.
+
+          This option will enlarge your kernel by about 7 KB. If unsure,
+          answer Y. This will only work if you said Y to "DOS FAT fs support"
+          as well. To compile this as a module, choose M here: the module will
+          be called msdos.
+
+config VFAT_FS

+        help
+          This option provides support for normal Windows file systems with
+          long filenames.  That includes non-compressed FAT-based file systems
+          used by Windows 95, Windows 98, Windows NT 4.0, and the Unix
+          programs from the mtools package.
+
+          The VFAT support enlarges your kernel by about 10 KB and it only
+          works if you said Y to the "DOS FAT fs support" above.  Please read
+          the file <file:Documentation/filesystems/vfat.txt> for details.  If
+          unsure, say Y.
+
+          To compile this as a module, choose M here: the module will be called
+          vfat.

+          that most of your FAT filesystems use, and can be overridden
+          with the "iocharset" mount option for FAT filesystems.
+          Note that "utf8" is not recommended for FAT filesystems.
+          If unsure, you shouldn't set "utf8" here.

+          To compile this file system support as a module, choose M here: the
+          module will be called ntfs.

+config NTFS_DEBUG
+        bool "NTFS debugging support"
+        depends on NTFS_FS
+        help
+          If you are experiencing any problems with the NTFS file system, say
+          Y here.  This will result in additional consistency checks to be
+          performed by the driver as well as additional debugging messages to
+          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
+          slowdown of the system.
+
+          When reporting bugs, please try to have available a full dump of
+          debugging messages while the misbehaviour was occurring.
+
+config NTFS_RW
+        bool "NTFS write support"
+        depends on NTFS_FS
+        help
+          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.
+
+          This is currently useful with TopologiLinux.  TopologiLinux is run
+          on top of any DOS/Microsoft Windows system without partitioning your
+          hard disk.  Unlike other Linux distributions TopologiLinux does not
+          need its own partition.  For more information see
+          <http://topologi-linux.sourceforge.net/>
+
+          It is perfectly safe to say N here.

+
+          Balanced trees are more efficient than traditional file system
+          architectural foundations.
+
+          In general, ReiserFS is as fast as ext2, but is very efficient with
+          large directories and small files.  Additional patches are needed
+          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.
+
+          Sponsored by Threshold Networks, Emusic.com, and Bigstorage.com.

+          and all blocks are packed to minimise data overhead. Block sizes
+          greater than 4K are supported up to a maximum of 1 Mbytes (default
+          block size 128K).  SquashFS 4.0 supports 64 bit filesystems and files
+          (larger than 4GB), full uid/gid information, hard links and
+          timestamps.  
+
+          Squashfs is intended for general read-only filesystem use, for
+          archival use (i.e. in cases where a .tar.gz file may be used), and in
+          embedded systems where low overhead is needed.  Further information

+        The sysfs filesystem is a virtual filesystem that the kernel uses to
+        export internal kernel objects, their attributes, and their
+        relationships to one another.
+
+        Users can use sysfs to ascertain useful information about the running
+        kernel, such as the devices the kernel has discovered on each bus and
+        which driver each is bound to. sysfs can also be used to tune devices
+        and other kernel subsystems.
+
+        Some system agents rely on the information in sysfs to operate.
+        /sbin/hotplug uses device and object attributes in sysfs to assist in
+        delegating policy decisions, like persistently naming devices.
+
+        sysfs is currently used by the block subsystem to mount the root
+        partition.  If sysfs is disabled you must specify the boot device on
+        the kernel boot command line via its major and minor numbers.  For
+        example, "root=03:01" for /dev/hda1.
+
+        Designers of embedded systems may wish to say N here to conserve space.
