Zezere is the Fedora IoT device provisioning service. It is the
software that runs *provision.fedoraproject.org*, but it can be
self-hosted (if you can figure it out; there is no documentation
whatsoever).
The main use case for running Zezere locally is to automatically add
trusted SSH public keys to Fedora IoT devices, without depending on a
cloud service. This playbook sets up Zezere with the very minimal
configuration needed to meet this goal.
