A few more days of tinkering and my initial #Vagrant setup has evolved to a nice little #Saltstack lab environment.
So I renamed the repo accordingly:
https://github.com/jbowdre/vagrant-saltlab
I'm having a lot of fun figuring things out, like how a top file is used to automatically assign states to minions. Having this ready-to-go-at-the-drop-of-a-hat lab is going to be a big help on my learning journey.
