Hi
Think I have had a miss understanding of the scope of
puppet variables
hiera data..
Think I have been mixing the two
I think my question here is how do you use hiera() in side a yaml to look
up info outside that current yaml.
so if hiera has check 1.yaml then 2.yaml then 3.yaml. How does 3.yaml get
info from the 1.yaml ???
