When creating a Featurized export that contains a panelizer_defaults component for an entity (such as a node type), the entity isn't panelized on a fresh installation.

This is resolved by separately exporting a Panelizer variable (panelizer_defaults_node_[type]) and also enabling Page Manager's listening to node/%node_view, which can be accomplished by defining the 'page_manager_node_view_disabled' variable and setting it to FALSE.

As a site builder, I would expect that the panelizer_defaults component would contain all of the configuration necessary for my Panelized entities to be enabled when the feature is reverted.

For an example of how we used this approach in the Commons_Groups module, see:
http://drupalcode.org/project/commons_groups.git/blob/refs/heads/7.x-3.x...
http://drupalcode.org/project/commons_groups.git/blob/refs/heads/7.x-3.x...

Marking this issue as documentation but leaving open in case Panelizer should cause additional components to be auto-detected in an export.
