ChefDK, Test Kitchen Driven NTP Cookbook

This gist uses TK+Berkshelf to drive creating a vagrant virts and converging a simple recipe to install and configure NTPd. This is a simple cookbook that has one recipe, one template (for ntp.conf) and one attribute file. It works on Ubuntu 12.04 and CentOS 6.4 (and derviatives) and the attribute file is used to support both distros.

This should work on Mac (where I developed it) and any chef-supported Linux that you can get Vagrant onto (Ubuntu/CentOS).

Because I use ChefDK and Test Kitchen, I can largely ignore setting up Vagrant and Berkshelf and can get right to work on writing recipe code.
