	help
	  This is the journaling version of the Second extended file system
	  (often called ext3), the de facto standard Linux file system
	  (method to organize files on a storage device) for hard disks.

	  The journaling code included in this driver means you do not have
	  to run e2fsck (file system checker) on your file systems after a
	  crash.  The journal keeps track of any changes that were being made
	  at the time the system crashed, and can ensure that your file system
	  is consistent without the need for a lengthy check.

	  Other than adding the journal to the file system, the on-disk format
	  of ext3 is identical to ext2.  It is possible to freely switch
	  between using the ext3 driver and the ext2 driver, as long as the
	  file system has been cleanly unmounted, or e2fsck is run on the file
	  system.

	  To add a journal on an existing ext2 file system or change the
	  behavior of ext3 file systems, you can use the tune2fs utility ("man
	  tune2fs").  To modify attributes of files and directories on ext3
	  file systems, use chattr ("man chattr").  You need to be using
	  e2fsprogs version 1.20 or later in order to create ext3 journals
	  (available at <http://sourceforge.net/projects/e2fsprogs/>).

	  To compile this file system support as a module, choose M here: the
	  module will be called ext3.  Be aware however that the file system
	  of your root partition (the one containing the directory /) cannot
	  be compiled as a module, and so this may be dangerous.

	  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.''

	  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

	  It is now also becoming possible to read and write compressed FAT
	  file systems; read <file:Documentation/filesystems/fat_cvf.txt> for

	  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://linux-ntfs.sourceforge.net/>.

	  To compile this file system support as a module, choose M here: the

config NTFS_DEBUG

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

	  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.

	  This is a virtual file system providing information about the status

	  your hard disk: the files are created on the fly by the kernel when
	  you try to access them. Also, you cannot read the files with older
	  version of the program less: you need to use more or cat.

	  It's totally cool; for example, "cat /proc/interrupts" gives
	  information about what the different IRQs are used for at the moment
	  (there is a small number of Interrupt ReQuest lines in your computer
	  that are used by the attached devices to gain the CPU's attention --
	  often a source of trouble if two devices are mistakenly configured
	  to use the same IRQ). The program procinfo to display some
	  information about your system gathered from the /proc file system.

	  Before you can use the /proc file system, it has to be mounted,
	  meaning it has to be given a location in the directory hierarchy.
	  That location should be /proc. A command such as "mount -t proc proc
	  /proc" or the equivalent line in /etc/fstab does the job.

	  The /proc file system is explained in the file

	delegating policy decisions, like persistantly naming devices.

	sysfs is currently used by the block subsystem to mount the root

	  This option enables applications to perform uncached I/O on files

	  is set for a file, its data is not cached in the system's page
	  cache.  Data is moved to and from user-level application buffers
	  directly.  Unlike local disk-based file systems, NFS O_DIRECT has
	  no alignment restrictions.

	  Unless your program is designed to use O_DIRECT properly, you are
	  much better off allowing the NFS client to manage data caching for
	  you.  Misusing O_DIRECT can cause poor server performance or network
	  storms.  This kernel build option defaults OFF to avoid exposing
	  system administrators unwittingly to a potentially hazardous
	  feature.

	  For more details on NFS O_DIRECT, see fs/nfs/direct.c.

	  If unsure, say N.  This reduces the size of the NFS client, and

	  SMB (Server Message Block) is the protocol Windows for Workgroups

	  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/>)

	  The intent of the cifs module is to provide an advanced
	  network file system client for mounting to CIFS compliant servers, 
	  including support for dfs (hierarchical name space), secure per-user
	  session establishment, safe distributed caching (oplock), optional
	  packet signing, Unicode and other internationalization improvements, 
	  and optional Winbind (nsswitch) integration. You do not need to enable
	  cifs if running only a (Samba) server. It is possible to enable both
	  smbfs and cifs (e.g. if you are using CIFS for accessing Windows 2003
	  and Samba 3 servers, and smbfs for accessing old servers). If you need
