Dhcp client configuration in 7.0

Hello to you all!

Prior to 7.0 I was using this line in /etc/dhclient.conf
supersede domain-name-servers 127.0.0.1;
so that I do not get the DNS from the ISP provider.

I am using unbound to resolve my queries. With the new changes I can not
get the same functionality.

I tried to add this in /etc/dhcpleased.conf
interface urtwn0 ignore dns
where urtwn0 is my interface or disable resolvd.

If resolvd is on I get my ISP DNS server, if not when unbound starts
resolvd adds the ISP DNS server to resolv.conf.

Can you please tell me what am I doing wrong and how can I have only
127.0.0.1 on the resolv.conf file?

Thank you!
