I have automated myself out of a job. Here's how to use the installer to create a new host:
1. Boot into installer
1. Enable Secure Boot Setup Mode on the target device's UEFI menu - this will vary depending on the manufacturer
2. Connect to the internet with `sudo nmcli device wifi connect "<SSID>" [--ask]`
2. Boot into the installer
3. Run `sudo nix-install /etc/nixos -m install|repair -h host [-k key] [-c] [-r]"`
3. Connect to the internet with `sudo nmcli device wifi connect "<SSID>" [--ask]`
4. Run `sudo nix-install /etc/nixos -m install|repair -s -h host [-k key] [-c] [-r]"`
