forget, so why not document it for everyone

-### Raspberry Pi 3: 32-bit or 64-bit

-It is possible to run the RPi 2 images on an RPi 3, as the RPi 3's CPU supports
-both the Armv8 and Armv7 instruction sets. The difference between these images
-is that the RPi 2 provides a 32-bit system with packages from the Void `armv7l`
-repositories, while the RPi 3 image provides a 64-bit system with packages from
-the Void `aarch64` repositories.
