This is hysterical! As I mentioned before I was using pump prior to the
conversion and since the conversion pump cannot grab an IP. So I have
statically been putting in the IP that my windows box grabs to at least
have connectivity. So...as a test I uninstalled pump and apt-getted
dhcpcd. Without any other confguration other than setting the interface I
can now grab an IP no problem! ;)
