[chef] Re: Re: Re: Automate the attributes used in chef

[Mark Harrison < >]

If you have a JSON file with nested attributes, then you'll need to
modify the script to walk the tree and generate attributes as
appropriate. It all depends on what you have in the json file and what
you want the output to look like. The script can be tweaked as needed
to do that. This idea is also based on already having a json file that
you would rather not manually type out an attributes file for. If you
don't have that, then just write the attributes file out, complete
with conditionals, comments and so on.
