Experimental flakes support is required. https://www.tweag.io/blog/2020-07-31-nixos-flakes/
sudo nixos-rebuild switch --flake .#hostname
#host-name is optional sudo nixos-rebuild --flake . will use the current name of the host.
Note: untracked files won't be copied to store. Use git add first, to build from a dirty directory.
To update nixpkgs input to latest unstable:
nix flake update --update-input nixpkgs
Create a minimal install media with all required tools and kernel modules using the following command:
nix build .\#nixosConfigurations.iso-minimal.config.system.build.isoImage
Write the resulting iso to a USB stick:
sudo dd bs=4M conv=fsync oflag=direct status=progress if=result/iso/*.iso of=/dev/sdX
- Boot prepared install media
- Clone the repo to some directory
- Run the installation
nixos-install --flake /path/to/repo#-new-host
For the initial install
nix run nix-darwin -- switch --flake .
Afer that, just
darwin-rebuild switch --flake .
