+
+logrotate is rotating already rotated atop's logs
+=================================================
+
+The existing logrotate configuration improperly rotates the log
+file which is not necessary due to the daily restart of atop. The
+binary retention is now handled via a new atop retention cron.
+The fix removes the atop logrotate configuration.
