proposal for update to pf logging FAQ

Hello Guys,

The page http://www.openbsd.org/faq/pf/logging.html has a section named "Packet Logging Through Syslog" containing an example script pflogrotate. This is a great example, however it won't work with OpenBSD 4.7. The problem is that pflogd no longer has a .pid file in /var/run as indicated in the script. I will suggest that the pkill style signalling (used also in /etc/newsyslog.conf) is used instead. That way the script will read:

/etc/pflogrotate (for 4.7)

	#!/bin/sh
	PFLOG=/var/log/pflog
	FILE=/var/log/pflog5min.$(date "+%Y%m%d%H%M")
	pkill -ALRM -u root -U root -t - -x pflogd
	if [ -r $PFLOG ] && [ $(stat -f %z $PFLOG) -gt 24 ]; then
	   mv $PFLOG $FILE
	   pkill -HUP -u root -U root -t - -x pflogd
	   tcpdump -n -e -ttt -r $FILE | logger -t pf -p local0.info
	   rm $FILE
	fi

Thank you so much for a truly great OS.

Sincerely,
