Overlay and sample configuration.nix which can be used to build an installer
image for Novena laptop.
To build either natively or using cross compilation toolchain, use
./build.sh
dd if=result-img/sd-image/nixos-novena-sd-image-20.09pre-git-armv7l-linux.img \
of=/dev/mmcblkX \
bs=1M
Proceed according to standard NixOS installation instructions. Don't forget to clone this repository and import the overlay.
In configuration.nix, select the custom kernel with
boot.kernelPackages = pkgs.linuxPackages_nvn
If using cross-compiled installer the initial installation might take several days
as Nix cannot reuse cross-compiled packages from installers /nix/store and
has to build whole world from scratch including bootstrap packages. Make sure to
supply additional cooling or limit the compilation to 3 cores with --option cores 3.
