# before the normal internet interfaces, which means they are always

# queries go from 0ms to 10+ or 100+ ms. To reverse the ordering, you
# can do:
#sudo sed -i --follow-symlinks '/tun\*\|tap\*/d' /etc/resolvconf/interface-order
# however, this breaks dns lookup for hosts on the openvpn lan.
# I can\'t figure out why hosts on the normal lan would not be
# broken under the default ordering, except the host I was
