     Builds system given a list of system names which are placed within your hosts/ directory. Note that each system has its own directory in hosts/ as well.

     A minimal configuration requires the file configuration.nix within each system directory, this will be the base config that is used across both NisOS and home-manager, specific optional files can also be added, hardware.nix for NisOS configuration and home.nix for home-manager configuration.

     The second parameter is the root of your configuration, which should be ./. in most cases.

     # Inputs

     `systems`

     : a list of strings with hostnames

     `root`

     : the root path of your configuration
