With 'set 3 boot on' the error 'file system "/boot" is not a FAT EFI system partition (ESP) file system' occurs when running "nixos-install" during the basic installation (tested in in a VirtualBox VM).
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.
