Firecracker: start a VM in less than a second

But it turns out that Firecracker is relatively straightforward to use (or at least as straightforward as anything else that's for running VMs), the documentation and examples are pretty clear, you definitely don't need to be a cloud provider to use it, and as advertised, it starts VMs really fast!
So I wanted to write about using Firecracker from a more DIY "I just want to run some VMs" perspective.
I'll start out by talking about what I'm using it for, and then I'll explain a few things I learned about it along the way.
