Eli Ribble 3993b526a5 Convert from cloud-init networking to static networking 
This is honestly pretty ugly. The issue is that I want two different
IPv6 addresses on this server. I get one address for free as part of my
hosting agreement. The other I have to pay $0.01 per month for. The
address is routable, but it's not provided via cloud-init like the
initial address.

I therefore took the data from /var/lib/cloud/instance/network-config.json
and translated it into this configuration manually. It's dangerous - I
don't know when any of this information may change.

However, it works, and both addresses are now bound to eth0.

Notice that I set the network configuration name to "09-wan". This is
because the previous configuration using cloud-init created a network
configuration at /etc/systemd/network/10-cloud-init that has to be
manually removed or superseded.

Eli Ribble 99f0311a38 Fix error around --impure 
I was seeing a stack trace with this at the bottom:

       error: cannot look up '<home-manager/nixos>' in pure evaluation mode (use '--impure' to override)

After reading a bit at https://nixos-and-flakes.thiscute.world/nixos-with-flakes/start-using-home-manager
I was able to craft this shape which uses home-manager in a flake and
doesn't have the same problem.
