- If you want your Linux box to act as an NFS *server*, so that other
- computers on your local network which support NFS can access certain
- directories on your box transparently, you have two options: you can
- use the self-contained user space program nfsd, in which case you
- should say N here, or you can say Y and use the kernel based NFS
- server. The advantage of the kernel based solution is that it is
- faster.
-
- In either case, you will need support software; the respective
- locations are given in the file <file:Documentation/Changes> in the
- NFS section.
-
- If you say Y here, you will get support for version 2 of the NFS
- protocol (NFSv2). If you also want NFSv3, say Y to the next question
- as well.
-
- Please read the NFS-HOWTO, available from
- <http://www.tldp.org/docs.html#howto>.

- To compile the NFS server support as a module, choose M here: the
- module will be called nfsd. If unsure, say N.

+ Choose Y here if you want to allow other computers to access

+ 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.

+ CONFIG_NFSD is selected.

- CONFIG_NFS_V3_ACL option. If unsure, say N.
+ 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.
