-          Balanced trees are more efficient than traditional file system

-          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

+          NCP (NetWare Core Protocol) is a protocol that runs over IPX and is
+          used by Novell NetWare clients to talk to file servers.  It is to
+          IPX what NFS is to TCP/IP, if that helps.  Saying Y here allows you
+          to mount NetWare file server volumes and to access them just like
+          any other Unix directory.  For details, please read the file
+          <file:Documentation/filesystems/ncpfs.txt> in the kernel source and
+          the IPX-HOWTO from <http://www.tldp.org/docs.html#howto>.
+          You do not have to say Y here if you want your Linux box to act as a
+          file *server* for Novell NetWare clients.
+          General information about how to connect Linux, Windows machines and
+          Macs is on the WWW at <http://www.eats.com/linux_mac_win.html>.
+          To compile this as a module, choose M here: the module will be called
+          ncpfs.  Say N unless you are connected to a Novell network.

+          Saying Y or M here enables read support.  There is partial, but
+          safe, write support available.  For write support you must also
+          say Y to "NTFS write support" below.
+          There are also a number of user-space tools available, called
+          ntfsprogs.  These include ntfsundelete and ntfsresize, that work
+          without NTFS support enabled in the kernel.
+          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>
+          and <http://www.linux-ntfs.org/>.
+          To compile this file system support as a module, choose M here: the
+          module will be called ntfs.
+          If you are not using Windows NT, 2000, XP or 2003 in addition to
+          Linux on your computer it is safe to say N.

+        help

+          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

+          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

+          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

+        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.

+          experimental, so you should back up your UFS partitions beforehand.
+config UFS_DEBUG
+        bool "UFS debugging"
+        depends on UFS_FS
+        help
