Cool thanks for the info.
I just have to figure out how
to get the machine to do that.
i.g. through dispatcher.d or network/interfaces.
one thing that I'm noticing is ubuntu's version of
NetworkManager only has two plugins(01ifupdown,keyfile);
I'll try loading another version and see if the other plugins
is what I'm missing to have dbusd transition
correctly.
