Reconsider the terminology around "persistence"
We inherited this terminology from the world of live distributions but during the discussions about the Tor Browser confinment and the Greeter revamp, several people raise issues about it.
It might be worth thinking about that and see if we can find something better (and otherwise be happy with it but for a good reason).
We should be really careful while doing that as it could impact many many place in our project (website, documentation, code, even infrastructure). So feasibility, cost effectivness and flexibility are important issues here as well.
