This is taken from the 18.09 change, which was reverted on release-18.09 but not master. The now-false 18.09 release notes were just removed from master in 29854e24265457991448afb93363bdcc9e5d2eca, but since the underlying change is still there, release notes for 19.03 are warranted. This commit takes the now-reverted release notes and reuses them for that.
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.
