This is a nice little patch we use to purge out /dev/klog after 
/etc/rc.d/dmesg and before /usr/local/etc/rc.d/syslog-ng.sh.

It's useful for shops that translate user.info facility/priority syslog 
messages into SMS/E-Mail via a log{} mechanism (i.e., hardware error 
messages from the kernel, like some flunky in the NOC plugging a keyboard 
into your system).

It lets you avoid 200 lines of boot messages in log(9) making their way 
into your log{} mechanism or into your pager.

We want to feed it upstream because we think others will find it useful.
