config EXT3_FS
	tristate "Ext3 journalling file system support"
	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

	  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

	  diskettes with FAT-based file systems and transparently access the
	  files on them, i.e. MSDOS files will look and behave just like all

	  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

	  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

	  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

	  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

	The sysfs filesystem is a virtual filesystem that the kernel uses to

	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

	help
	  If you are connected to some other (usually local) Unix computer
	  (using SLIP, PLIP, PPP or Ethernet) and want to mount files residing
	  on that computer (the NFS server) using the Network File Sharing
	  protocol, say Y. "Mounting files" means that the client can access
	  the files with usual UNIX commands as if they were sitting on the
	  client's hard disk. For this to work, the server must run the
	  programs nfsd and mountd (but does not need to have NFS file system
	  support enabled in its kernel). NFS is explained in the Network
	  Administrator's Guide, available from
	  <http://www.tldp.org/docs.html#guide>, on its man page: "man
	  nfs", and in the NFS-HOWTO.

	  A superior but less widely used alternative to NFS is provided by
	  the Coda file system; see "Coda file system support" below.

	  If you say Y here, you should have said Y to TCP/IP networking also.
	  This option would enlarge your kernel by about 27 KB.

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

	  If you are configuring a diskless machine which will mount its root
	  file system over NFS at boot time, say Y here and to "Kernel
	  level IP autoconfiguration" above and to "Root file system on NFS"
	  below. You cannot compile this driver as a module in this case.
	  There are two packages designed for booting diskless machines over
	  the net: netboot, available from
	  <http://ftp1.sourceforge.net/netboot/>, and Etherboot,
	  available from <http://ftp1.sourceforge.net/etherboot/>.

	  If you don't know what all this is about, say N.

config NFS_V3
	bool "Provide NFSv3 client support"
	depends on NFS_FS
	help
	  Say Y here if you want your NFS client to be able to speak version
	  3 of the NFS protocol.

	  If unsure, say Y.

config NFS_V4
	bool "Provide NFSv4 client support (EXPERIMENTAL)"
	depends on NFS_FS && EXPERIMENTAL
	select RPCSEC_GSS_KRB5
	help
	  Say Y here if you want your NFS client to be able to speak the newer
	  version 4 of the NFS protocol.

	  Note: Requires auxiliary userspace daemons which may be found on
		http://www.citi.umich.edu/projects/nfsv4/

	  If unsure, say N.

config NFS_DIRECTIO
	bool "Allow direct I/O on NFS files (EXPERIMENTAL)"
	depends on NFS_FS && EXPERIMENTAL
	help
	  This option enables applications to perform uncached I/O on files
	  in NFS file systems using the O_DIRECT open() flag.  When O_DIRECT
	  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
	  causes open() to return EINVAL if a file residing in NFS is
	  opened with the O_DIRECT flag.

	select EXPORTFS
	help
	  If you want your Linux box to act as an NFS *server*, so that other
	  computers on your local network which support NFS can access certain
	  directories on your box transparently, you have two options: you can
	  use the self-contained user space program nfsd, in which case you
	  should say N here, or you can say Y and use the kernel based NFS
	  server. The advantage of the kernel based solution is that it is
	  faster.

	  In either case, you will need support software; the respective
	  locations are given in the file <file:Documentation/Changes> in the
	  NFS section.

	  If you say Y here, you will get support for version 2 of the NFS
	  protocol (NFSv2). If you also want NFSv3, say Y to the next question
	  as well.

	  Please read the NFS-HOWTO, available from
	  <http://www.tldp.org/docs.html#howto>.

	  To compile the NFS server support as a module, choose M here: the
	  module will be called nfsd.  If unsure, say N.

config NFSD_V3

	  If you would like to include the NFSv4 server as well as the NFSv2

	  If unsure, say N.

config NFSD_TCP

config ROOT_NFS

	help
	  If you want your Linux box to mount its whole root file system (the
	  one containing the directory /) from some other computer over the
	  net via NFS (presumably because your box doesn't have a hard disk),
	  say Y. Read <file:Documentation/nfsroot.txt> for details. It is
	  likely that in this case, you also want to say Y to "Kernel level IP
	  autoconfiguration" so that your box can discover its network address
	  at boot time.

config SMB_FS

	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.

config SMB_NLS_REMOTE
	string "Default Remote NLS Option"
	depends on SMB_NLS_DEFAULT
	default "cp437"

	  This setting allows you to specify a default value for which
	  codepage the server uses. If this field is left blank no
	  translations will be done by default. The local codepage/charset
	  default to CONFIG_NLS_DEFAULT.

	  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.

config CIFS
	tristate "CIFS support (advanced network filesystem for Samba, Window and other CIFS compliant servers)"
	depends on INET
	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

          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.

        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.

config CIFS_EXPERIMENTAL

	  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

config CODA_FS
	tristate "Coda file system support (advanced network fs)"
	depends on INET
	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
