dhcpcd is part of system set and present in all Funtoo stages. It can be a very good dhcp client for simple, automatically assigned wired and wireless connections.
Add dhcpcd to the default runlevel
# rc-update add dhcpcd default
and then start dhcpcd by updating the runlevels and launching anything not already started with
# /etc/init.d/dhcpcd start
to start dhcpcd specifically.
For simple dhcp configurations it is sufficient for getting network connection. More advanced settings are described in corresponding
dhcpcd.conf man pages.
