  13 # This ExecStartPre business is a hack to inject a key for the mgr daemon,
  14 # using whatever key already exists on the mon on this node to gain sufficient
  15 # permissions to create the mgr key.  Failure is ignored at every step (the
  16 # '-' prefix) in case someone has already used some other trick to set
  17 # everything up manually.
  18 # `sh -c "exec ..."` is required, since different Linux ditributives have different rules on absolute paths of that executables.
  19 # systemd requires to use absoulte paths.
