+ 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.

+ 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.

+ This option enables support in your system's NFS server for

+
+ 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/.
