Where do the boot time messages go?

[Ronald F. Guilmette]

In my /etc/rc.conf file, I have the following (among other things):

firewall_enable="YES"
firewall_type="/etc/fw.rules"
firewall_logging="YES"

And of course, on my system, the /etc/fw.rules file is full of ipfw
"add" commands.

During a normal boot of FreeBSD, I can see those add commands being
processed.  They are shown, briefly, whizzing by, on the console.

During a recent reboot, I also saw something at about the same time
that looked like it might possibly have been some sort of ipfw error
or warning message.

I would like to investigate.

Unfortunately it appears that all of the console messages that are
being logged, during the time when ipfw is processing my local firewall
rules file, are not in fact stored into either /var/log/messages nor
even into /var/log/security.  (I know.  I looked.)

So, um, where do these messages go, exactly?

I really would like to have a look at the ones from the last boot.
