It doesn't. Dnsmasq only ever forwards DNS requests to other nameservers which
can do iterative queries.

You can't go by those files. In Quantal, NM sends nameserver addresses to
dnsmasq via D-Bus.
How to see what NM has told dnsmasq:
nmcli -f IP4 dev list | grep DNS

The latter file is created by the standalone dnsmasq server. When the
latter is started with its initscript, the initscript registers the
address 127.0.0.1 with resolvconf. If all is well then the standalone
dnsmasq server instance uses the NM-controlled dnsmasq instance as its
sole upstream nameserver, but perhaps this isn't happening in your case
because of some some misconfiguration.
If you don't want to use the standalone dnsmasq server then it's best to
purge the "dnsmasq" package. Leave the "dnsmasq-base" package installed:
it includes the dnsmasq binary which is used both by NetworkManager and
by the "dnsmasq" package.

Title:
network-manager doesn't configure DNS properly and name resolution
fails
Status in “network-manager” package in Ubuntu:
Incomplete
Bug description:
My network is configured in such a way that I can only exit through a
HTTP proxy and the this it is set with proxy.pac so for getting the
proxy configuration I also need the DNS to work...
When using dnsmasq for DNS, dnsmasq is getting started by network-
manager, /etc/resolv.conf is pointing to localhost, but dnsmasq is
unable to resolv any DNS names. In my network dnsmasq should not try
to connect directly to the DNS root servers(which it looks like it
does), but it should just use the DNS servers I get through DHCP. But
there is nothing telling it to use them, since both /var/run/nm-dns-
dnsmasq.conf and /etc/NetworkManager/dnsmasq.d (which dnsmasq is set
to use when started by network-manager) are empty.
-when not using dnsmasq for DNS in network-manager, I get the right
DNS servers set inside /run/resolvconf/interface/NetworkManager, but
resolvconf just won't use them, since it keeps getting localhost from
/run/resolvconf/interface/lo.dnsmasq. The problem goes away after
removing this file and restarting resolvconf.
I think the problem can be worked around in two ways:
-if using dnsmasq, network-manager should configure the reachable name
servers in /etc/NetworkManager/dnsmasq.d
-if using just resolvconf, /run/resolvconf/interface/lo.dnsmasq should not be
created.
Ubuntu version: 12.10
network-manager version: 0.9.6.0-0ubuntu7
expected results: DNS resolution should work
current status: DNS resolution does not work unless I do a workaround each
time I connect to the network
