This reverts commit 66967ec7521d065f605795d64ddbbbd4fcd448c3, reversing changes made to fb6595eafdb90ef0bc7a31c2bfc9204e4cad11d9. Fixes #70442; discussion: https://github.com/NixOS/nixpkgs/pull/70027
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.
