How Many Are Talking, Dalton?

Ubuntu touch when it was gifted to us by Canonical had an update system and still does called system image. There is a delta system inside of system image where the server checks for each tar ball in a series. It'll check each one against its last version and then do any additions or removals as required there. And what we ended up with was, okay, install Ubuntu touch, install all the keys and stuff to it from the server and then delete user bin on all Nexus 5 models in a certain release channel. But the good news is no one actually using it in production.
