  config NFSD
  	tristate "NFS server support"
  	depends on INET
  	depends on FILE_LOCKING
  	select LOCKD
  	select SUNRPC
  	select EXPORTFS
  	select NFS_ACL_SUPPORT if NFSD_V2_ACL
  	help
  	  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 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"
  	depends on NFSD && PROC_FS
  	select NFSD_V3
  	select FS_POSIX_ACL
  	select SUNRPC_GSS
  	select CRYPTO
  	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.
  
  config NFSD_V4_SECURITY_LABEL
  	bool "Provide Security Label support for NFSv4 server"
  	depends on NFSD_V4 && SECURITY
  	help
  
  	Say Y here if you want enable fine-grained security label attribute
  	support for NFS version 4.  Security labels allow security modules like
  	SELinux and Smack to label files to facilitate enforcement of their policies.
  	Without this an NFSv4 mount will have the same label on each file.
  
  	If you do not wish to enable fine-grained security labels SELinux or
  	Smack policies on NFSv4 files, say N.
  
  	WARNING: there is still a chance of backwards-incompatible protocol changes.
  	For now we recommend "Y" only for developers and testers.
  
  config NFSD_FAULT_INJECTION
  	bool "NFS server manual fault injection"
  	depends on NFSD_V4 && DEBUG_KERNEL
  	help
  	  This option enables support for manually injecting faults
  	  into the NFS server.  This is intended to be used for
  	  testing error recovery on the NFS client.
  
  	  If unsure, say N.
