+-- have been installed, but before %postun scripts in packages get
+-- executed. %transfiletriggerun gets the right list of files
+-- but it is invoked too early (before changes happen).
+-- %filetriggerpostun happens at the right time, but it fires for
+-- every package.
+-- To execute the reload at the right time, we create a state
+-- file in %transfiletriggerun and execute the daemon-reload in
+-- the first %filetriggerpostun.
