>Description:
For some time now the release notes for REL6 have indicated that ipv6_enable should disable all ipv6 support.  It still doesn't as of beta2.

There is clearly a push for people to run GENERIC, but choices like this make it completely impossible for security-conscious sites to do so.  Can we please provide an option to completely disable ipv6 support in /etc/rc.conf?
>How-To-Repeat:
Put ipv6_enable in /etc/rc.conf

Reboot

ifconfig -a shows inet6 information for each interface.
netstat -nr shows numerous ipv6 routes.
