# authconfig -- class reference for platform-specific implementation of

# service    -- class reference for platform-specific implementation of a 

#               PlatformService class 

# knownservices -- factory instance to access named services IPA cares about, 

#                  names are ipapython.services.wellknownservices 

# backup_and_replace_hostname -- platform-specific way to set hostname and 

#                                make it persistent over reboots 

# restore_network_configuration -- platform-specific way of restoring network 

#                                  configuration (e.g. static hostname) 

# restore_context -- platform-sepcific way to restore security context, if 

#                    applicable 

# check_selinux_status -- platform-specific way to see if SELinux is enabled 

#                         and restorecon is installed.
