Some observations:

• When using balenalib base images BALENA_ARCH images result in smaller images when compared to BALENA_MACHINE_NAME images
• Best current result is:
  • For aarch64 use entware + opkg --> ~40MB image size
  • For generic arch use:
    • node --> ~110MB image size
    • dockerize--> ~76MB image size
