/proc/kmsgを使用するとsyslog-ngの起動が失敗する

最近でsyslog-ngからまで更新しています。アップグレード後、次のエラーメッセージでデーモンは起動しません。3.7.33.13.2

[2017-12-23T20:42:40.635915] Error checking the uniqueness of the persist names, please override it with persist-name option. Shutting down.; persist_name='affile_sd_curpos(/proc/kmsg)', location='/etc/syslog-ng/syslog-ng.conf:24:5'

参考までに、構成の24行目を参照してください。以下の記事全体をご覧ください。

   file("/proc/kmsg");

しばらくこのエラーを調査してきましたが、このpersist-nameオプションは問題を解決しません。意図された使用はこの問題とは関係がないようです。

私が使用する設定ファイルは、強化されたGentooのデフォルト設定ファイルです。
