Comment 42 for bug 1003842

One thing needs to be checked, though. Reading dnsmasq(8):

 -o, --strict-order
              By default, dnsmasq will send queries to any of the
              upstream servers it knows about and tries to favour
              servers that are known to be up. Setting this flag
              forces dnsmasq to try each query with each server
              strictly in the order they appear in /etc/resolv.conf

Will switching on strict-order have the same effect now that nameserver addresses are sent over D-Bus?
