13 Choose Y here if you want to allow other computers to access
14 files residing on this system using Sun's Network File System
15 protocol. To compile the NFS server support as a module,
16 choose M here: the module will be called nfsd.
17
18 You may choose to use a user-space NFS server instead, in which
19 case you can choose N here.
20
21 To export local file systems using NFS, you also need to install
22 user space programs which can be found in the Linux nfs-utils
23 package, available from http://linux-nfs.org/. More detail about
24 the Linux NFS server implementation is available via the
25 exports(5) man page.
26
27 Below you can choose which versions of the NFS protocol are
28 available to clients mounting the NFS server on this system.
29 Support for NFS version 2 (RFC 1094) is always available when
30 CONFIG_NFSD is selected.
31
32 If unsure, say N.

51 help
52 Solaris NFS servers support an auxiliary NFSv3 ACL protocol that
53 never became an official part of the NFS version 3 protocol.
54 This protocol extension allows applications on NFS clients to
55 manipulate POSIX Access Control Lists on files residing on NFS
56 servers. NFS servers enforce POSIX ACLs on local files whether
57 this protocol is available or not.
58
59 This option enables support in your system's NFS server for the
60 NFSv3 ACL protocol extension allowing NFS clients to manipulate
61 POSIX ACLs on files exported by your system's NFS server. NFS
62 clients which support the Solaris NFSv3 ACL protocol can then
63 access and modify ACLs on your NFS server.
64
65 To store ACLs on your NFS server, you also need to enable ACL-
66 related CONFIG options for your local file systems of choice.
67
68 If unsure, say N.

79 This option enables support in your system's NFS server for
80 version 4 of the NFS protocol (RFC 3530).
81
82 To export files using NFSv4, you need to install additional user

84 available from http://linux-nfs.org/.

141 Say Y here if you want enable fine-grained security label attribute
142 support for NFS version 4. Security labels allow security modules like
143 SELinux and Smack to label files to facilitate enforcement of their policies.
144 Without this an NFSv4 mount will have the same label on each file.
