to build:

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

query with:

nix flake show

secrets

we use sops for secrets. see helpers/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 (e.g. change fstab UUIDs) refer to flake.nix for more details
