  42 -- executed for some reason.
  43 -- On upgrade, we need to run daemon-reload after any new unit files
  44 -- have been installed, but before %postun scripts in packages get
  45 -- executed. %transfiletriggerun gets the right list of files
  46 -- but it is invoked too early (before changes happen).
  47 -- %filetriggerpostun happens at the right time, but it fires for
  48 -- every package.
  49 -- To execute the reload at the right time, we create a state
  50 -- file in %transfiletriggerun and execute the daemon-reload in
  51 -- the first %filetriggerpostun.
