Since nix 2.0 the no-build-hook option was replaced by the builders options that allows to override remote builders ad-hoc. Since it is useful to disable remote builders updating nixos without network, this commit reintroduces the option.
To build the manual, you need Nix installed on your system (no need
for NixOS). To install Nix, follow the instructions at
https://nixos.org/nix/download.html
When you have Nix on your system, in the root directory of the project
(i.e., `nixpkgs`), run:
nix-build nixos/release.nix -A manual.x86_64-linux
When this command successfully finishes, it will tell you where the
manual got generated.
