+On some specially patched kernels, and when exporting filesystems that
+support ACLs, this option tells nfsd not to reveal ACLs to clients, so
+they will see only a subset of actual permissions on the given file
+system.  This option is safe for filesystems used by NFSv2 clients and
+old NFSv3 clients that perform access decisions locally.  Current
+NFSv3 clients use the ACCESS RPC to perform all access decisions on
+the server.  Note that the

+option only has effect on kernels specially patched to support it, and

+with ACL support (i.e. by default,
+.I no_acl
+is off).
