[pkg-lighttpd] Bug#560837: lighttpd listened on ipv6 only after upgrade

[Stefan Bühler]

Looks like you don't understand the problem. We ("upstream") know perfectly 
well that IPV6_V6ONLY would have made things easier, but we don't like 
breaking existing setups, so we didn't change it. In our next version 
(lighttpd sandbox/2.0) we already use IPV6_V6ONLY, and have a better syntax 
for listening to multiple sockets.

I would recommend to just drop the ipv6-enabled script. The people who care 
about ipv6 listening should just enable it manually; i think it is bad style 
to silently change existing setups to listen to ipv6, as it might circumvent 
access restrictions.
