I did not know about /proc/sys/kernel/printk, or that dmesg had the capability
to set it, just like klogd.  Learn something new all the time.

I was using the unix-stream source for /dev/log.  Might be good to explain the
need to use the datagram source for klogd in the reference docs, although I
don't see why anyone would want to use it now.  I only tried it because of the
console logging issue, which Sandor's suggestion has solved nicely.

Thanks for the quick responses.

Bruce
