MaaS = ubuntu 15
Nodes = ubuntu 14

Using maas: 1.7.6+bzr3376-0ubuntu2~15.04.1

The node fails after a PXE boot curtain install request. Cloud init info from node:

Specifics that I do have concern over

looking up the hostname via "nslookup high-pin" does not work, however "nslookup high-pin.maas" does. the resolv.conf does not contain a search domain. Is this normal for a curtain install?

nslookup, apt-get upgrade, apt-get update, ping, all work and routing.

This node was working 1 day ago, the only thing I can think of is possibly the maas log might help? It did update to a new version of the image via a sync.

Any ideas on how to chase down what I might need to tweak to fix this?
