[Bug 959037] Re: NM-controlled dnsmasq prevents other DNS servers from running, yet network-manager doesn't Conflict with their packages

[Thomas Hood]

Alkis: Suppose your host, foo, has external IP address 10.1.2.3 and runs
a standalone nameserver which listens on eth0.  Configure things such
that nm-dnsmasq on foo uses 10.1.2.3 as its upstream nameserver;
configure the standalone nameserver on foo not to listen on lo.  If it's
dnsmasq, start it with --except-interface=lo.  Does this do what you
want?

If so then this may be a very simple way to deal with #959037, at least
with respect to dnsmasq.  Network-manager simply drops a file with

    except-interface=lo

into /etc/dnsmasq.d/.  NM can still use the local standalone dnsmasq via
the external network interface, the address of which it may receive from
the DHCP server, for example.
