cfengine_enterprise_federation:federation_manage_files

Prototype: cfengine_enterprise_federation:federation_manage_files

Description: Manage files, directories and permissions in $(cfengine_enterprise_federation:config.federation_dir)

By default the import process will not prohibit the inclusion of duplicate hostkey data from feeders. By defining the cfengine_mp_fr_handle_duplicate_hostkeys class in augments a step will be performed during import which will find the which feeder's data is most recent for each duplicate hostkey and use that data. Duplicate hostkey data will be moved to a dup schema for analysis.

This class only applies to superhubs.
