I haven't tested this in a while (and don't feel like rebooting to test it now), but last time I set NETWORKING_IPV6=no resulted in IPV6 initialization not being performed, _BUT_ enough IPV6 initialization was done (possibly due to module autoloading?) to result in the ipv6 module loading (and that's enough for later programs to do pointless (in a non-IPV6 environment) IPv6 queries/connects/sockets etc.) Cheers, MaZe.
