Automatically deploy CoreOS server on Proxmox

For my Kubernetes experiments I wanted automated CoreOS deployments. I managed to do that by abusing the smbios1 fields in the qemu configuration of a VM on Proxmox.

Using Ignition to run a one-time systemd service which sets the ip address and gateway, and the 'core' user's initial password, so my ansible scripts can come in and install CoreOS.

Installing cloud-init on a fresh Raspbian Lite image

This is a work in Progress!

Purpose

This mainly demonstrates my goal of preparing a Raspberry Pi to be provisioned prior to its first boot. To do this I have chosen to use the same cloud-init that is the standard for provisioning servers at Amazon EC2, Microsoft Azure, OpenStack, etc.

I found this to be quite challenging because there is little information available for using cloud-init without a cloud. So, this project also servers as a demonstration for anyone on any version of Linux who may want to install from source, and/or use without a cloud. If you fall into that later group, you probably just want to read the code. It's bash so everything I do, you could also do at the command line. (Even the for loop.)
