the generic bootloader will allow more code-sharing with rpi and pinephone. desko should soon use the generic bootloader as well. problems: lappy can't boot from USB stick. it makes it to the initrd, but there's no dev nodes for the USB drive. unsure if this is how it was before, too. |

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
admin tips
online: https://nixos.wiki/wiki/Cheatsheet
verify ALL nix store contents with:
sudo nix-store --verify --check-contents # add the --repair flag to auto-repair as well
search for a package with:
nix search nixpkgs <query string>
find which package owns some file with:
nix-locate /bin/vim # or any other package-relative path
