Bug#701884: kfreebsd: unknown method 'inet6 auto'
Control: tags -1 serious
Justification: if an IPv6 route announcement is seen at install time,
the kfreebsd-* system would have no network connectivity on first boot,
ifup will fail and even the loopback interface will not be set up.
Also IPv6 and GNU/kFreeBSD are both still release goals I believe.
This has been fixed in sid for some time but we absolutely must see it
fixed in wheezy.
