This allows setting options for the same LUKS device in different modules. For example, the auto-generated hardware-configuration.nix can contain boot.initrd.luks.devices.crypted.device = "/dev/disk/..."; while configuration.nix can add boot.initrd.luks.devices.crypted.allowDiscards = true; Also updated the examples/docs to use /disk/disk/by-uuid instead of /dev/sda, since we shouldn't promote the use of the latter.
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.
