Correct.  Each PANOS device that's managed via Panorama has a local 
persistent configuration that includes device-specific things like local 
management address, HA-pair, user accounts...
Panorama stores in it's config a bunch of rulesets and templates that can 
be applied to the managed devices; when it pushes those to a managed device 
they're merged at runtime into that device's live config, but not part of 
that box's actual local config.
