You cannot make a machine which needs a secret run fully unattended
without having such secret *somewhere*. You can move pieces around,
separate roles amongst different parts, protect a secret in a way that
a _different_ secret is needed instead, etc. But in the end, as the
machine needs that secret, you need to store it there. Or,
alternatively, have a human input it and have it stored in memory, with
the caveat that the machine won't be able to boot to a fully functional
state until that is provided.
