Resolv.conf not populated with ipv6 dns
First, I searched for this issue but didn't find the exact same issue being reported. I apologize if I missed it.
Anyways, I was running the snapshot from June 1st but then I upgraded to the June 32rd snapshot and this issue began. With the June 1st snapshot, I would see ipv6 and ipv4 dns entries on the main page of the webgui. I never looked in /var/etc/resolv.conf so I can only assume they were in there as well. When I upgraded to June 23rd's snapshot, only ipv4 dns entries from my ISP show up and they are the only ones actually used. Hosts on the LAN still get both the ipv4 and ipv6 dns addresses of the pfsense box.
I have "Allow DNS server list to be overridden by DHCP/PPP on WAN" checked.
My ISP offers native dual-stack via DHCP6-PD. Poking around, I find that /var/etc/nameserver_v6wan has the ipv6 entries from my ISP. /var/etc/nameserver_vr1 has the ipv4 entries from my ISP. Lastly, /var/etc/resolv.conf only has localhost and the ipv4 entries only and no ipv6 entries. The June 1st snapshot definitely used both ipv4 and ipv6 dns entries. I remember seeing that in the state table.

It should be noted that there is no newline at the end of nameserver_v6wan.
