 Administration FAQ
 ==================
 
-.. topic:: Duplicate log entries when using :func:`log()` function
+.. _administration-faq-duplicate-log-entries:
 
-  Because GenieACS uses a full fledged scripting language for device
-  configuration, the only way to guarantee that it has satisfied the 'desired
-  state' is by repeatedly executing the script until there's no more
-  discrepancies with the current device state. Though it may seem like this
-  will cause duplicate requests going to the device, this isn't actually the
-  case because device configuration are stated declaratively and that the
-  scripts themselves are pure functions in the context of a session (e.g.
-  Date.now() always returns the same value within the session).
+Duplicate log entries when using :func:`log()` function
+-------------------------------------------------------
 
-  To illustrate with an example, consider the following script:

+
+  log("Executing script");
   declare("Device.param", null, {value: 1});
   commit();
   declare("Device.param", null, {value: 2});
 
-  This will set the value of the 'Device.param' to 1, then to 2. Then as the
-  script is run again the value is set back to 1 and so on. A stable state will
-  never be reached so GenieACS will execute the script a few times until it
-  gives up and throws a fault. This is an edge case that should be avoided. A
-  more typical case is where the script is run once or twice. Essentially if an
-  execution doesn't result in any request to the CPE or a change in the data
-  model then a stable state is deemed to have been reached.

+
+Configurations not pushed to device after factory reset
+---------------------------------------------------------
+
+After a device is reset to its factory default state, the cached data model in
+GenieACS's database needs to be invalidated to force rediscovery. Ensure the
+following lines are called on ``0 BOOTSTRAP`` event:
+
+.. code:: javascript
+
+  const now = Date.now();
+
+  // Clear cached data model to force a refresh
+  clear("Device", now);
+  clear("InternetGatewayDevice", now);
+
+
+Most device parameters are missing
+----------------------------------
+
+For performance reasons (server, client, and network), GenieACS by default only
+fetches parts of the data model that are necessary to satisfy the declarations
+in your provision scripts. Create declarations for any parameters you need
+fetched by default.
+
+If you're unsure and want to explore the available parameters exposed by the
+device, refresh the root parameter (e.g. ``InternetGatewayDevice``) from
+GenieACS's UI. You typically only need to do that one time for a given CPE
+model.
