[Saku Ytti]

Hey Andrew,

We largely do not use any in-device tooling for configuration generation,
as that creates vendor dependencies we try to add sparingly. All data is
formal data in SQL and we turn this formal data into informal router
configuration via templates.
We consider router configurations immutable, we never change
configurations, we only reassign it. Not unlike in purely functional
programming.
