Hi I was wondering if there is a way to have a role var defined under  
defaults to reference a group\_var. Basically i would like one file to  
change if specifics need to be defined per deployment/site. Here is a  
quick diagram to perhaps explain it better:

group\_vars  
&nbsp;&nbsp;&nbsp;&nbsp;all \<--- master vars  
roles/  
&nbsp;&nbsp;&nbsp;&nbsp;common/  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;defaults/  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;main.yml \<-- sub vars referecing master vars

Can this be done?
