How can one run several dhcpd on a single machine?

Hi. Thanks for replies.
As you may know recently I've posted about long dhcpd.conf parsing
time (https://lists.isc.org/pipermail/dhcp-users/2009-May/008905.html).
I have done as you Glenn suggested, and it took about 27 minutes.
So after that we decided simply to run several dhcpd instances each
for certain range of subnets. Parsing that small files takes just a
few seconds.
Soon after I posted the question I found out that providing a pid file
solves the problem. So now we have several dhcpd's running at once on
different interfaces.
Thanks.
