deploying to SD card

• build a toplevel config: nix build '.#hostSystems.moby'
• mount a system:
  • mkdir -p root/{nix,boot}
  • mount /dev/sdX1 root/boot
  • mount /dev/sdX2 root/nix
• copy the config:
  • sudo nix copy --no-check-sigs --to root/ $(readlink result)
    • nix will copy stuff to root/nix/store
• install the boot files:
  • sudo /nix/store/sbwpwngjlgw4f736ay9hgi69pj3fdwk5-extlinux-conf-builder.sh -d ./root/boot -t 5 -c $(readlink ./result)
