Managed using Nix flakes and home-manager.
To setup, symlink flake.nix to /etc/nixos/flake.nix, and run nixos-rebuild switch.
To build and remotely deploy, nixos-rebuild switch can be used as well.
For example, to build on localhost and deploy to ipos, run: nixos-rebuild switch --flake .#ipos --target-host root@ipos --build-host localhost
