Replacing Android device with a new one

So.... TILLW, if you have a new android phone, the very first thing you want to do is tell it you want to copy an existing phone you have in your possession. There appears to be no way (other than resetting the phone back to factory defaults) after the first screen to have one phone be setup like another. This is inane.

TIL it ain't so easy to enable root login in ubuntu

So... TIL today. You can enable root login in sshd_config. You can set a password for the root as well of course. However, you can't actually ssh into the box if you have any keys (or at least "some" keys) in your ssh-agent. So, by running ssh-agent bash and then logging in as root to target, I get asked for a password. If I alternatively have an ssh key you get the message that
Please login as the user "ubuntu" rather than the user "root".
