>Description:
In /etc/rc.conf set:
  ipv6_default_interface="ed0"

See error messages on boot because route(8) no longer supports the -cloning flag and network.subr network6_default_interface_setup() has not been updated to reflect this.

route: bad keyword: cloning
usage: route [-dnqtv] command [[modifiers] args]

The man-page for route(8) still documents -cloning.
>How-To-Repeat:
Install FreeBSD 8.0, try to set a default interface for link-local traffic (such as pinging ff02::2) per /etc/defaults/rc.conf and previous experience on FreeBSD 7.
