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

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

88
89 Say Y here if you want enable fine-grained security label attribute
90 support for NFS version 4. Security labels allow security modules like
91 SELinux and Smack to label files to facilitate enforcement of their policies.
92 Without this an NFSv4 mount will have the same label on each file.
93
94 If you do not wish to enable fine-grained security labels SELinux or
95 Smack policies on NFSv4 files, say N.
96
97 WARNING: there is still a chance of backwards-incompatible protocol changes.
98 For now we recommend "Y" only for developers and testers."
