Initial flake implementation
For now, simply copied current configuration.nix and hardware-configuration.nix
to hostname specific directory.
Made minor modifications to remove input impurity from
hardware-configuration.nix (<nixpkgs> to 4{modulesPath}).
Created flake.nix to import the configuration.nix and just build it.
Referred to this guy : https://github.com/MatthewCroughan/nixcfg
