+Subject: [PATCH] xinetd should be able to listen on IPv6 even in -inetd_compat mode
+
+xinetd does not bind to IPv6 addresses (and does not seem to have an
+option to do so) when used in -inetd_compat mode.  As current inetd's
+are IPv6-aware, this is a problem: this means xinetd cannot be used as
+a drop-in inetd replacement.
+
+The attached patch is a suggestion: it adds a -inetd_ipv6 global
+option that, if used, causes inetd-compatibility lines to have an
+implicit "IPv6" option.  Perhaps this is not the best solution, but
+there should definitely be a way to get inetd.conf to be read in
+IPv6-aware mode.
