There is work ongoing in NETCONF to provide different pieces for
bootstrapping.

- draft-ietf-netconf-keystore

  a model for managing keys
  
- draft-ietf-netconf-netconf-client-server

  a model for managing NETCONF client and server config

- draft-ietf-netconf-restconf-client-server

  a model for managing RESTCONF client and server config

- draft-ietf-netconf-ssh-client-server

  a model providing NETCONF over SSH config details

- draft-ietf-netconf-tls-client-server
 
  a model providing NETCONF over TLS config details

- draft-ietf-netconf-zerotouch

  a mechanism for loading bootstrapping information

When and how is up to the controller design. The fully functioning
protocol falls out of the YANG data model - once you have YANG data
model, you are ready to go. That said, there is a currently expired
WG document providing more details.

https://tools.ietf.org/html/draft-ietf-lmap-restconf-03

The idea here was just provide an explanation how the LMAP data model
works together with RESTCONF.
