	  Choose Y here if you want to allow other computers to access
	  files residing on this system using Sun's Network File System
	  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 3 (RFC 1813) is always available when
	  CONFIG_NFSD is selected.

	  If unsure, say N.

	default n
	help
	  NFSv2 (RFC 1094) was the first publicly-released version of NFS.
	  Unless you are hosting ancient (1990's era) NFS clients, you don't
	  need this.

	  If unsure, say N.

config NFSD_V2_ACL
	bool "NFS server support for the NFSv2 ACL protocol extension"
	depends on NFSD_V2

config NFSD_V3_ACL
	bool "NFS server support for the NFSv3 ACL protocol extension"
	depends on NFSD
	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.
