As the number of DHCP clients served by a dhcpd instance
increases, the size of the syslog tends towards infinity,
since every single client request is logged. This might be
useful for debugging purposes, but it needs to be possible
to turn it off. I have patched dhcpd for this purpose and
have run it on my system for a couple days, but it has
received no wider testing than that. See the referenced URL.

I would like to suggest that the reduced logging mode be
made the default, as it is for all other packages. Imagine
if httpd or named were to try to log each and every
transaction they perform with a client...
