Currently the AiO installer requires the user to generate and trust SSH keys for access from it's local host to the target machine. When the target machine is also localhost (which we expect to be the case for many users) this is still required because ansible is executed from within a confined container environment and needs to SSH into the host it is running on.

In this cases it is reasonable to automate the SSH generation and trust in
~/.ssh/authorized_keys. After the playbook runs the keys should be removed from the trust.
