* boot target from NixOS installer USB
* passwd for nixos user on target
* note IP address, test that ssh as nixos works
* on target: nixos-generate-config --no-filesystems, copy to base host
* on target: dd if=/dev/random of=/dev/disk/by-id/<usb drive for encryption key> bs=4096 count=1
* on target: dd if=/dev/disk/by-id/<usb drive for encryption key> of=key.bin bs=4096 count=1
* copy key.bin to hosts/<target>/
* use the generated config to create new config in hosts/<target>
* set the actual device IDs in hosts/<target>/disk-config.nix
* on base host: nix run github:nix-community/nixos-anywhere -- --flake '.#<target>' nixos@<target IP>
* after confirmed working, update hosts/<target>disk-config.nix to set keyFile to /dev/sdX (otherwise when the USB drive fails it's harder to replace)
