Build a custom log entry on a DHCPACK CentOS 6.

[Mark Haney]

We've got a custom log entry created that's based on whether the
agent.circuit-id exists.  The problem is that the circuit-id gets included
in DHCPDISCOVER and DHCPOFFER, so we're getting duplicate custom messages
logged.

What we want to do it create this custom log file, with the circuit-id only
on the DHCPACK.  The log creation params are below.  We use this so that
customers can get a web interface view of the current leases.

Is there a way to do this with the latest CentOS 6 dhcpd package?

----
if exists agent.circuit-id
 {
        log (info, concat( "DHCPUSER:,", concat (suffix (concat ("0",
binary-to-ascii (16, 8, "", substring( hardware, 1, 1))),2), ":", suffix
(concat ("0", binary-to-ascii (16, 8, "",substring( hardware, 2, 1))),2),
":", suffix (concat ("0", binary-to-ascii(16, 8, "", substring( hardware,
3, 1))),2), ":", suffix (concat ("0", binary-to-ascii (16, 8, "",
substring( hardware, 4, 1))),2),":", suffix (concat ("0", binary-to-ascii
(16, 8, "", substring( hardware, 5, 1))),2), ":", suffix (concat ("0",
binary-to-ascii (16, 8, "", substring( hardware, 6, 1))),2)), ",IP:,",
binary-to-ascii (10, 8, ".", leased-address), ",CID:,", option
agent.circuit-id));
 }
