  31 -- have been installed, but before %postun scripts in packages get
  32 -- executed. %transfiletriggerun gets the right list of files
  33 -- but it is invoked too early (before changes happen).

  35 -- every package.
  36 -- To execute the reload at the right time, we create a state
  37 -- file in %transfiletriggerun and execute the daemon-reload in
  38 -- the first %filetriggerpostun.
