-.IR no_acl
-On some specially patched kernels, and when exporting filesystems that
-support ACLs, this option tells
-.B 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
-.I no_acl
-option only has effect on kernels specially patched to support it, and
-when exporting filesystems with ACL support. The default is to export
-with ACL support (i.e. by default,
-.I no_acl
-is off).
