Commit 29d7d8f44df24d6876c527d442eb42aee7227d6b has introduced another section with the ID "sec-release-19.09-incompatibilities", which subsequently causes the build to fail. I just merged both sections and the manual is now building again. Signed-off-by: aszlig <aszlig@nix.build>
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.
