After seeing this article, I just migrated from Dinghy to Dlite. I saved about 5GB of disk space, got much faster VM startup time and basically no hassle. It was a cinch to work my docker-compose startup into a LaunchAgent and now I finally have all my services running on boot. I highly recommend giving it a shot; my eyes nearly popped when I saw how quickly it downloaded and started the VM (must have been all of a 10MB download).
