Comment 7 for bug 1586400

We are doing a last minute push to get "ubuntu-core" renamed to "core", so that the images going out on RTM have the logic in place for testing, but this is unrelated to the topic here. This specific bug is simply about having the "core" snap with the "core" type, and this transition needs to be done without breaking current snaps out there.

So yes, the build system needs to change to generate "core" snaps with the "core" type, but that's not urgent as snapd cannot refuse to take a "os" type snap any time soon.
