Automatically start tmpnb on boot

[reaganch]

The jupyterhub wiki describes a way to start jupyterhub automatically at startup as a system service: https://github.com/jupyterhub/jupyterhub/wiki/Run-jupyterhub-as-a-system-service

Is there a way to similarly host a tmpnb server automatically at startup, preferably as a system service as well?
