	  Squashfs is intended for general read-only filesystem use, for

	  If unsure, say N.

config NFS_V4

	help
	  This option enables support for version 4 of the NFS protocol
	  (RFC 3530) in the kernel's NFS client.

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

	  If unsure, say N.

config ROOT_NFS
	bool "Root file system on NFS"

	  If you want your system to mount its root file system via NFS,

	  protocol.  To compile the NFS server support as a module,
	  choose M here: the module will be called nfsd.

	  You may choose to use a user-space NFS server instead, in which
	  case you can choose N here.

	  To export local file systems using NFS, you also need to install
	  user space programs which can be found in the Linux nfs-utils
	  package, available from http://linux-nfs.org/.  More detail about
	  the Linux NFS server implementation is available via the
	  exports(5) man page.

	  Below you can choose which versions of the NFS protocol are
	  available to clients mounting the NFS server on this system.
	  Support for NFS version 2 (RFC 1094) is always available when
	  CONFIG_NFSD is selected.

config NFSD_V3

config NFSD_V3_ACL

	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 SUNRPC_REGISTER_V4

	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.

	  Secure RPC calls with Kerberos require an auxiliary user-space

config SMB_FS

	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.

config NCP_FS

	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

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
