When resolvconf is installed and NetworkManager connects/disconnects a
particular device, NM sends the nameserver configuration to resolvconf
and does not write /etc/resolv.conf directly, leaving resolv.conf
arbitration up to resolvconf.  Does anyone know of a way to get
debuginfo or whatever out of resolvconf so we can see what it's doing in
cases like this?  I'd like to add that info to the
NetworkManagerDebugging wiki page.  At least if NM is
writing /etc/resolv.conf it logs what it's doing to syslog...
