Adds a very basic shadowing test.
...
For the record, I'm aware that there's a lot here that I'm not testing. I think the smart move is to get towards a running machine and see which configurations it actually tries to set up, then follow along with appropriate testing; it might cause me to discover a flaw in my comprehension before I've made the same mistake in both the code and a test.
