  12           files residing on this system using Sun's Network File System
  13           protocol.  To compile the NFS server support as a module,
  14           choose M here: the module will be called nfsd.
  15
  16           You may choose to use a user-space NFS server instead, in which
  17           case you can choose N here.
  18
  19           To export local file systems using NFS, you also need to install
  20           user space programs which can be found in the Linux nfs-utils
  21           package, available from http://linux-nfs.org/.  More detail about
  22           the Linux NFS server implementation is available via the
  23           exports(5) man page.
  24
  25           Below you can choose which versions of the NFS protocol are
  26           available to clients mounting the NFS server on this system.
  27           Support for NFS version 2 (RFC 1094) is always available when
  28           CONFIG_NFSD is selected.

  30           If unsure, say N.

  49         help
  50           Solaris NFS servers support an auxiliary NFSv3 ACL protocol that
  51           never became an official part of the NFS version 3 protocol.
  52           This protocol extension allows applications on NFS clients to
  53           manipulate POSIX Access Control Lists on files residing on NFS
  54           servers.  NFS servers enforce POSIX ACLs on local files whether
  55           this protocol is available or not.
  56
  57           This option enables support in your system's NFS server for the
  58           NFSv3 ACL protocol extension allowing NFS clients to manipulate
  59           POSIX ACLs on files exported by your system's NFS server.  NFS
  60           clients which support the Solaris NFSv3 ACL protocol can then
  61           access and modify ACLs on your NFS server.
  62
  63           To store ACLs on your NFS server, you also need to enable ACL-
  64           related CONFIG options for your local file systems of choice.
  65
  66           If unsure, say N.

  79
  80           To export files using NFSv4, you need to install additional user
  81           space programs which can be found in the Linux nfs-utils package,
  82           available from http://linux-nfs.org/.

  90           This option enables support for the parallel NFS features of the

 100
 101         Say Y here if you want enable fine-grained security label attribute
 102         support for NFS version 4.  Security labels allow security modules like
 103         SELinux and Smack to label files to facilitate enforcement of their policies.
 104         Without this an NFSv4 mount will have the same label on each file.
 105
 106         If you do not wish to enable fine-grained security labels SELinux or
 107         Smack policies on NFSv4 files, say N.

 112         help
 113           This option enables support for manually injecting faults
 114           into the NFS server.  This is intended to be used for
 115           testing error recovery on the NFS client.
