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.
15      You may choose to use a user-space NFS server instead, in which
16      case you can choose N here.
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 More detail about
21      the Linux NFS server implementation is available via the
22      exports(5) man page.
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.
29      If unsure, say N.

35    help
36      The syscall interface to nfsd was obsoleted in 2.6.0 by a new
37      filesystem based interface. The old interface is due for removal
38      in 2.6.40. If you wish to remove the interface before then
39      say N.

59    select NFSD_V2_ACL
60    help
61      Solaris NFS servers support an auxiliary NFSv3 ACL protocol that
62      never became an official part of the NFS version 3 protocol.
63      This protocol extension allows applications on NFS clients to
64      manipulate POSIX Access Control Lists on files residing on NFS
65      servers. NFS servers enforce POSIX ACLs on local files whether
66      this protocol is available or not.
68      This option enables support in your system's NFS server for the
69      NFSv3 ACL protocol extension allowing NFS clients to manipulate
70      POSIX ACLs on files exported by your system's NFS server. NFS
71      clients which support the Solaris NFSv3 ACL protocol can then
72      access and modify ACLs on your NFS server.
74      To store ACLs on your NFS server, you also need to enable ACL-
75      related CONFIG options for your local file systems of choice.
77      If unsure, say N.

87      This option enables support in your system's NFS server for
88      version 4 of the NFS protocol (RFC 3530).
90      To export files using NFSv4, you need to install additional user
91      space programs which can be found in the Linux nfs-utils package,
