I'm want to use local dnsmasq. I added this line to dhclient.conf:
prepend domain-name-servers 127.0.0.1;
But got in resolv.conf *ONLY* "127.0.0.1", and no NS from dhclient.
This problem exists starting from FreeBSD-10, on some older release this options was worked properly.
I was meant to report this a short while ago on CURRENT:
I think the append/prepend issue affects more than just 'domain-name-server' as well.
I'm not checked all prepend options, but option "prepend domain-name" works propely.
