He goes on to describe the painful process of building a large snap on a Raspberry Pi 2 just in order to release an armhf version. Thankfully, nowadays there's a better way. "Snapcraft still doesn't fully support cross-building, but the Launchpad team recently introduced snap builders for several different architectures that run on very high-end hardware-- available for free, for everyone! The only downside is that they aren't very well documented. Maybe I can help with that."
