When I write my column, I try to stick to specific hacks or tips you can

and configuration file examples. This time, however, I take a
step off this tried-and-true path of tech tips and instead talk about
more-general, high-level concepts, strategies and, frankly, personal opinions

I was proudly wearing one of my Salt Stack shirts the other day when my daughter
