I now have a virtual hierarchy level for setting up my lower memory
settings when using vagrant/virtualbox.
The gms settings are in an example-puppet-master.yaml file in the
nodes directory which are needed for the instructions.
I thought I needed to double quote items that had interpolated
variables but it turns out I don't need to which is good
because I effectively can't due to .to_yaml not doing what I
wanted it to do.
