First install the service from the CLFS Bootscripts package:
tar -xvf bootscripts-cross-lfs-2.0.0.tar.xz cd bootscripts-cross-lfs-2.0.0 make install-service-dhcpcd
          Finally, create the /etc/sysconfig/network-devices/ifconfig.eth0/dhcpcd
          configuration file using the following commands. Adjust
          appropriately for additional interfaces:
        
cd /etc/sysconfig/network-devices &&
mkdir -v ifconfig.eth0 &&
cat > ifconfig.eth0/dhcpcd << "EOF"
ONBOOT="yes"
SERVICE="dhcpcd"
# Start Command for DHCPCD
DHCP_START="-q"
# Stop Command for DHCPCD
DHCP_STOP="-k"
EOF
        
          The values of these variables must be changed in every file to
          match the proper setup. If the ONBOOT
          variable is set to “yes” the
          network script will bring up the Network Interface Card (NIC)
          during booting of the system. If set to anything but
          “yes” the NIC will be
          ignored by the network script and not be brought up.
        
          The SERVICE variable defines the method
          used for obtaining the IP address. The CLFS-Bootscripts package has
          a modular IP assignment format, and creating additional files in
          the /etc/sysconfig/network-devices/services directory
          allows other IP assignment methods.
        
          The DHCP_START and DHCP_STOP variables arguments that are passed onto
          dhcpcd when starting and stoppping
          the service. More information about what can be passed can be found
          in the dhcpcd(8) man page.
