Comment 5 for bug 1586400

We went back and forth on this issue a bit, but I believe the latest agreement is actually that we want snaps of type "core" indeed. There's no reason to keep the inconsistency of naming something "os" internally when everything else refers to those as "core".

We'll need to support snaps with the old "os" type for quite a while as these are out there, but I'd like to deprecate them sooner rather than later, and refer to these as "core" consistently.

Also, we've agreed that "personal" will actually be built on the same "core" snap, as that's going to be much nicer to work with and maintain.
