This is based from how devos link:https://github.com/divnix/digga/blob/760bb9c29063258ba547145de0ab96acd7eba4c0/modules/bootstrap-iso.nix[generates their ISO].
You can also see link:https://nix.dev/tutorials/building-bootable-iso-image[an example from nix.dev].
To make use of this, you can generate an ISO through link:https://github.com/nix-community/nixos-generators[nixos-generators]. footnote:[You can also try this for other hosts as well for MORE BEEFY OFFLINE INSTALLATION MEDIUM!]
