search domA.example.org domB.example.org # [NOTE I made these up, but the form is the same]

search domA.example.org

I want the search setting to be just:

search domA.example.org

I've deleted the top/offending line, but every time I restart dnsmasq or run resolvconf -u (for example), the offending line comes back. Where is it getting the domB.example.org from? I've looked in all the usual places (I think), and tried "grep -R domB *" in /etc, but nothing turns up! I'm at a loss.

Any pointers on where I should look next?

Thanks,

Kevin
