Comment 7 for bug 1639646

Oliver: Thank you for the info. This is very helpful.

It would be great if this architecture was described somewhere.

A couple of new questions:
1) If I create an image for my Raspberry Pi 3, and go through all of the configuration steps but never login with ssh, then change my private key and update my public key with Ubuntu One. I assume that I need to login with ssh using my new private key, correct? The public key is not in the image, correct?
2) I assume that during the first login is the only time the Ubuntu Snappy contacts Ubuntu.com. It does not need to do this for every login, correct?
3) After logging in with ssh for the first time, is there a link that describes the process of updating the public key password on the Raspberry Pi?

Thanks again
