Maybe it could be considered a kernel bug: if ipv6 support is disabled
(because built as a module) at the time the netbase init script runs,
then it cannot enable bindv6only.  The sysctl errors out.

But surely programs should not be relying on bindv6only to be set!
That is just asking for trouble.  There _are_ going to be
administrators who disable it, and we should accomodate them.  In
other words, lighttpd needs to set or clear the IPV6_V6ONLY option
itself for ipv6 sockets.
