	  for NFS and quotas, please see <http://www.namesys.com/> for links.

	  It is more easily extended to have features currently found in

	  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
	  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

	  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,

	  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

config NTFS_DEBUG

	  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

	  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"

	  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

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

	  Support for NFS version 2 (RFC 1094) is always available when
	  CONFIG_NFSD is selected.

	  If unsure, say N.

config NFSD_V2_ACL
	bool
	depends on NFSD

config NFSD_V3
	bool "NFS server support for NFS version 3"
	depends on NFSD
	help
	  This option enables support in your system's NFS server for
	  version 3 of the NFS protocol (RFC 1813).

	  If unsure, say Y.

config NFSD_V3_ACL
	bool "NFS server support for the NFSv3 ACL protocol extension"
	depends on NFSD_V3
	select NFSD_V2_ACL
	help
	  Solaris NFS servers support an auxiliary NFSv3 ACL protocol that
	  never became an official part of the NFS version 3 protocol.
	  This protocol extension allows applications on NFS clients to
	  manipulate POSIX Access Control Lists on files residing on NFS
	  servers.  NFS servers enforce POSIX ACLs on local files whether
	  this protocol is available or not.

	  This option enables support in your system's NFS server for the
	  NFSv3 ACL protocol extension allowing NFS clients to manipulate
	  POSIX ACLs on files exported by your system's NFS server.  NFS
	  clients which support the Solaris NFSv3 ACL protocol can then
	  access and modify ACLs on your NFS server.

	  To store ACLs on your NFS server, you also need to enable ACL-
	  related CONFIG options for your local file systems of choice.

	  If unsure, say N.

config NFSD_V4
	bool "NFS server support for NFS version 4 (EXPERIMENTAL)"
	depends on NFSD && PROC_FS && EXPERIMENTAL
	select NFSD_V3

	select RPCSEC_GSS_KRB5
	help
	  This option enables support in your system's NFS server for
	  version 4 of the NFS protocol (RFC 3530).

	  To export files using NFSv4, you need to install additional user
	  space programs which can be found in the Linux nfs-utils package,
	  available from http://linux-nfs.org/.

	  If unsure, say N.

	  transport.

	  To compile RPC client RDMA transport support as a module,
	  choose M here: the module will be called xprtrdma.

config SUNRPC_REGISTER_V4
	bool "Register local RPC services via rpcbind v4 (EXPERIMENTAL)"
	depends on SUNRPC && EXPERIMENTAL
	default n
	help
	  Sun added support for registering RPC services at an IPv6
	  address by creating two new versions of the rpcbind protocol
	  (RFC 1833).

	  This option enables support in the kernel RPC server for
	  registering kernel RPC services via version 4 of the rpcbind
	  protocol.  If you enable this option, you must run a portmapper
	  daemon that supports rpcbind protocol version 4.

	  Serving NFS over IPv6 from knfsd (the kernel's NFS server)
	  requires that you enable this option and use a portmapper that
	  supports rpcbind version 4.

	  If unsure, say N to get traditional behavior (register kernel
	  RPC services using only rpcbind version 2).  Distributions
	  using the legacy Linux portmapper daemon must say N here.

config RPCSEC_GSS_KRB5

	select CRYPTO_CBC
	help
	  Choose Y here to enable Secure RPC using the Kerberos version 5
	  GSS-API mechanism (RFC 1964).

	  Secure RPC calls with Kerberos require an auxiliary user-space
	  daemon which may be found in the Linux nfs-utils package
	  available from http://linux-nfs.org/.  In addition, user-space
	  Kerberos support should be installed.

	  If unsure, say N.

config SMB_FS
	tristate "SMB file system support (OBSOLETE, please use CIFS)"
	depends on INET
	select NLS
	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"
	help
	  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 NCP_FS
	tristate "NCP file system support (to mount NetWare volumes)"
	depends on IPX!=n || INET
	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>.

	  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>.

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
	  module will be called coda.

config AFS_FS
