Commits 351d12437 ("nixos/release-notes: PHP config-file-scan-dir /etc -> /etc/php.d") 41c8aa8d6 ("php: change config-file-scan-dir from /etc to /etc/php.d") were merged to master _after_ NixOS 16.09. Commit 351d12437 then wrongly updated the NixSO 16.09 release notes. Fix by moving the entry to NixOS 17.03.
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.
