Dhcpcd is not Dhcpd

In rc.conf, if you configure your interface to use dhcp, like this:

interface=eth0
address=
netmask=
gateway=

dhcpcd will be started automatically from the network script found in /etc/rc.d and configured in /etc/rc.conf in the DAEMONS array

You can run to check it out for yourself

ps -ax
 710 ?        Ss     0:00 dhcpcd -q eth0

So, you don't need to add dhcpcd daemon

Configuration

Prevent dhcpcd to change /etc/resolv.conf

just add a line in /etc/dhcpcd.conf

nohook resolv.conf
