-	help
-	  Choose Y here if you want to access files residing on other
-	  computers using Sun's Network File System protocol.  To compile
-	  this file system support as a module, choose M here: the module
-	  will be called nfs.
-
-	  To mount file systems exported by NFS servers, you also need to
-	  install the user space mount.nfs command which can be found in
-	  the Linux nfs-utils package, available from http://linux-nfs.org/.
-	  Information about using the mount command is available in the
-	  mount(8) man page.  More detail about the Linux NFS client
-	  implementation is available via the nfs(5) man page.
-
-	  Below you can choose which versions of the NFS protocol are
-	  available in the kernel to mount NFS servers.  Support for NFS
-	  version 2 (RFC 1094) is always available when NFS_FS is selected.
-
-	  To configure a system which mounts its root file system via NFS
-	  at boot time, say Y here, select "Kernel level IP
-	  autoconfiguration" in the NETWORK menu, and select "Root file
-	  system on NFS" below.  You cannot compile this file system as a
-	  module in this case.

-config NFS_V3
-	bool "NFS client support for NFS version 3"
-	depends on NFS_FS
-	help
-	  This option enables support for version 3 of the NFS protocol
-	  (RFC 1813) in the kernel's NFS client.
-
-	  If unsure, say Y.
-
-config NFS_V3_ACL
-	bool "NFS client support for the NFSv3 ACL protocol extension"
-	depends on NFS_V3
-	help
-	  Some NFS servers support an auxiliary NFSv3 ACL protocol that
-	  Sun added to Solaris but 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
-	  ACLs on local files whether this protocol is available or not.
-
-	  Choose Y here if your NFS server supports the Solaris NFSv3 ACL
-	  protocol extension and you want your NFS client to allow
-	  applications to access and modify ACLs on files on the server.
-
-	  Most NFS servers don't support the Solaris NFSv3 ACL protocol
-	  extension.  You can choose N here or specify the "noacl" mount
-	  option to prevent your NFS client from trying to use the NFSv3
-	  ACL protocol.
-
-	  If unsure, say N.
-
-config NFS_V4
-	bool "NFS client support for NFS version 4 (EXPERIMENTAL)"
-	depends on NFS_FS && EXPERIMENTAL
-	select RPCSEC_GSS_KRB5
-	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"
-	depends on NFS_FS=y && IP_PNP
-	help
-	  If you want your system to mount its root file system via NFS,
-	  choose Y here.  This is common practice for managing systems
-	  without local permanent storage.  For details, read
-	  <file:Documentation/filesystems/nfsroot.txt>.
-
-	  Most people say N here.
