11 Choose Y here if you want to allow other computers to access
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.
29
30 If unsure, say N.

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.
