For those of you commenting about the mechanics and pitfalls, I've found that a Pi3B+ with the 7" screen and a keyboard/trackpad is a wonderful tool for provisioning new cards. I do headless system configuration on that, then swap to the Zero or whatever it'll actually use. Since the BSPs for every board are tiny, there's no reason to limit yourself to something that can't work on all of the boards out there. It makes troubleshooting a lot easier. Also, don't buy crap SD cards, and probably have 2x the number you'd like to have running. This stuff is cheap so that you can have multiples for testing.
