	  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.

	  If you like it, you can pay us to add new features to it that you
	  need, buy a support contract, or pay us to port it to another OS.

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
	tristate "VFAT (Windows-95) fs support"
	select FAT_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.

config FAT_DEFAULT_CODEPAGE
	int "Default codepage for FAT"
	depends on MSDOS_FS || VFAT_FS
	default 437
	help
	  This option should be set to the codepage of your FAT filesystems.
	  It can be overridden with the "codepage" mount option.
	  See <file:Documentation/filesystems/vfat.txt> for more information.

config FAT_DEFAULT_IOCHARSET
	string "Default iocharset for FAT"
	depends on VFAT_FS
	default "iso8859-1"
	help
	  Set this to the default input/output character set you'd
	  like FAT to use. It should probably match the character set
	  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.
	  See <file:Documentation/filesystems/vfat.txt> for more information.

config NTFS_FS
	tristate "NTFS file system support"
	select NLS
	help
	  NTFS is the file system of Microsoft Windows NT, 2000, XP and 2003.

	  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.

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.

	  SMB (Server Message Block) is the protocol Windows for Workgroups
	  (WfW), Windows 95/98, Windows NT and OS/2 Lan Manager use to share
	  files and printers over local networks.  Saying Y here allows you to
	  mount their file systems (often called "shares" in this context) and
	  access them just like any other Unix directory.  Currently, this
	  works only if the Windows machines use TCP/IP as the underlying
	  transport protocol, and not NetBEUI.  For details, read
	  <file:Documentation/filesystems/smbfs.txt> and the SMB-HOWTO,
	  available from <http://www.tldp.org/docs.html#howto>.

	  Note: if you just want your box to act as an SMB *server* and make
	  files and printing services available to Windows clients (which need
	  to have a TCP/IP stack), you don't need to say Y here; you can use
	  the program SAMBA (available from <ftp://ftp.samba.org/pub/samba/>)
	  for that.

	  General information about how to connect Linux, Windows machines and
	  Macs is on the WWW at <http://www.eats.com/linux_mac_win.html>.

	  Enabling this will make smbfs use nls translations by default. You

	  CONFIG_SMB_NLS_REMOTE.

	  The nls settings can be changed at mount time, if your smbmount

	  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

	  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/>.
