* [logrotate] Decrease frequency to every 10 minutes; kill any lingering logrotate processes * [logrotate] Delete all *.1.gz files as firstaction; Remove note about init-system-helpers < 1.47 workaround However, continue to send SIGHUP directly to rsyslogd process because 'service rsyslog rotate' still doesn't work properly with init-system-helpers version 1.48
