        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

          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.''

          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").

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

          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.

          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

          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"

          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>

          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.

          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

          This is a virtual file system providing information about the status

          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 sysfs filesystem is a virtual filesystem that the kernel uses to

        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 persistantly 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

        help
          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>.

          To compile the SMB support as a module, choose M here: the module will
          be called smbfs.  Most people say N, however.

config SMB_NLS_DEFAULT
        bool "Use a default NLS"
        depends on SMB_FS
        help
          Enabling this will make smbfs use nls translations by default. You
          need to specify the local charset (CONFIG_NLS_DEFAULT) in the nls
          settings and you need to give the default nls for the SMB server as
          CONFIG_SMB_NLS_REMOTE.

          The nls settings can be changed at mount time, if your smbmount
          supports that, using the codepage and iocharset parameters.

          smbmount from samba 2.2.0 or later supports this.

        select NLS
        help
          This is the client VFS module for the Common Internet File System
          (CIFS) protocol which is the successor to the Server Message Block 
          (SMB) protocol, the native file sharing mechanism for most early
          PC operating systems.  The CIFS protocol is fully supported by 
          file servers such as Windows 2000 (including Windows 2003, NT 4  
          and Windows XP) as well by Samba (which provides excellent CIFS
          server support for Linux and many other operating systems). Currently
          you must use the smbfs client filesystem to access older SMB servers
          such as Windows 9x and OS/2.

          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 
          to mount to Samba or Windows 2003 servers from this machine, say Y.

config CIFS_STATS

config CIFS_XATTR

          Extended attributes are name:value pairs associated with inodes by
          the kernel or by users (see the attr(5) manual page, or visit
          <http://acl.bestbits.at/> for details).  CIFS maps the name of
          extended attributes beginning with the user namespace prefix
          to SMB/CIFS EAs. EAs are stored on Windows servers without the
          user namespace prefix, but their names are seen by Linux cifs clients
          prefaced by the user namespace prefix. The system namespace
          (used by some filesystems to store ACLs) is not supported at
          this time.

        depends on CIFS_XATTR
        help
          Enabling this option will cause the cifs client to attempt to
          negotiate a newer dialect with servers, such as Samba 3.0.5
          or later, that optionally can handle more POSIX like (rather
          than Windows like) file behavior.  It also enables
          support for POSIX ACLs (getfacl and setfacl) to servers
          (such as Samba 3.10 and later) which can negotiate
          CIFS POSIX ACL support.  If unsure, say N.

        help
          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>.

config CODA_FS

        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.

          A new kernel-userspace API had to be introduced for Coda v6.0
          to support larger 128-bit file identifiers as needed by the
          new realms implementation.

          However this new API is not backward compatible with older
          clients. If you really need to run the old Coda userspace
          cache manager then say Y.
