to deploy:

nixos-rebuild --flake "./#servo" {build,switch}

if the target is the same as the host, nix will grab the hostname automatically:

nixos-rebuild --flake . {build,switch}

more options (like building packages defined in this repo):

nix flake show

secrets

i use sops for secrets. see modules/universal/secrets.nix for some tips.

building images

to build a distributable image (GPT-formatted image with rootfs and /boot partition):

nix build ./#imgs.lappy

this can then be dd'd onto a disk and directly booted from a EFI system. there's some post-processing to do before running a rebuild on the deployed system (deploying ssh keys, optionally changing fs UUIDs, etc). refer to flake.nix for more details.

building packages

to build one of the custom sane packages, just name it:

nix build ./#fluffychat-moby

to build a nixpkg:

nix build ./#nixpkgs.curl

to build a package for another platform:

nix build ./#packages.aarch64-linux.nixpkgs.ubootRaspberryPi4_64bit
