The devshell for the project incudes a convenient script for managing your
system called flk. Each of the following chapters is a reference for one of
its subcommands.
Without any of the subcommands, flk acts as a convenient shortcut for
nixos-rebuild:
flk NixOS buildWill build hosts/NixOS.nix. You can change out build for switch, test,
etc. Any additional arguments are passed through to the call to
nixos-rebuild.
