Yep. That is how I explained it previously.
The NM applet has all that info init, which is
why I thought it weird that NM decides to
NOT set up the default rout, and not put
the correct nameserver in resolv.conf.
But I will look into
/etc/NetworkManager/dnsmasq.d/
and set the nameserver there correctly.
