1795 Sun added support for registering RPC services at an IPv6
1796 address by creating two new versions of the rpcbind protocol
1797 (RFC 1833).
1798
1799 This option enables support in the kernel RPC server for
1800 registering kernel RPC services via version 4 of the rpcbind
1801 protocol. If you enable this option, you must run a portmapper
1802 daemon that supports rpcbind protocol version 4.
1803
1804 Serving NFS over IPv6 from knfsd (the kernel's NFS server)
1805 requires that you enable this option and use a portmapper that
1806 supports rpcbind version 4.
1807
1808 If unsure, say N to get traditional behavior (register kernel
1809 RPC services using only rpcbind version 2). Distributions
1810 using the legacy Linux portmapper daemon must say N here.
