-When adding a new host:
-1. install NixOS via the graphical installer
-2. `mv /etc/hardware-configuration ./devicename-hardware-configuration.nix`
-3. copy an existing devicename.nix
-5. change import to `new-devicename-hardware-configuration.nix`
-6. set the hostname and optional imports in `new-devicename.nix`
-7. `ln -s ./new-devicename.nix /etc/nixos/configuration.nix`
