+ A number of reports already filed against network-manager seem to
+ reflect this problem, but to make things very clear I am opening a new
+ report. Where appropriate I will mark other reports as duplicates of
+ this one.
+
+ Consider a pre-Precise system with the following /etc/resolv.conf:
+
+ nameserver 192.168.0.1
+ nameserver 8.8.8.8
+
+ The first address is the address of a nameserver on the LAN that can
+ resolve both private and public domain names. The second address is the
+ address of a nameserver on the Internet that can resolve only public
+ names.
+
+ This setup works fine because the GNU resolver always tries the first-
+ listed address first.
+
+ Now the administrator upgrades to Precise and instead of writing the
+ above to resolv.conf, NetworkManager writes
+
+ server=192.168.0.1
+ server=8.8.8.8
+
+ to /var/run/nm-dns-dnsmasq.conf and "nameserver 127.0.0.1" to
+ resolv.conf. Resolution of private domain names is now broken because
+ dnsmasq treats the two upstream nameservers as equals and uses the
+ faster one, which could be 8.8.8.8.
