Attempt from Ubuntu Precise client to mount nfs served by a RHEL7 server gets

The last time I saw similar things it was because Trusty had changed its nfs config to only export NFSv4 by default, so it should be pretty easy to fix by changing a config file/option in whatever does the imaging.

It looks like this just had to do with /etc/exports needing a dummy entry so the service could start and chef set to enable/start the service. When I manually did this I was able to mount nfs with nfsvers=3 so it doesn't look like it had anything to do with v3/v4 afterall:
