 To make it easier to deploy, test, break, tear down, and redeploy the environment:
 1. The Salt master blindly auto-accepts all minion keys.
 2. The minions register the `roles:saltlab` grain to aid in targeting.
-3. The contents of `srv/` get `rsync`ed to `/srv/` when the master starts up. *Note that this is a one-way `rsync` from host to VM (and not the other way around), so make sure to write your Salt content on the host and use `vagrant rsync` to push changes into the VM.*
