Thanks.  I used your script to create my rules file:

# cat /etc/udev/rules.d/70-persistent-net.rules

# Added by 'write_udev' for detected device 'eth0'.
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", 
ATTR{address}=="02:56:02:01:f3:b9", NAME="eth0"

And that looked good (right madaddr and device name).  So built my 
ifcfg-eth0:

# cat /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE="eth0"
BOOTPROTO=none
NM_CONTROLLED="no"
ONBOOT="yes"
TYPE="Ethernet"
NAME="System eth0"
MACADDR=02:67:15:00:01:78
MTU=1500
DNS1=208.83.67.188
GATEWAY="208.83.67.177"
IPADDR="208.83.67.178"
NETMASK="255.255.255.240"
HOSTNAME="miredo.htt-consult.com"
IPV6INIT="yes"
DNS2=2607:f4b8:3:3:9254:5400:0:188

Something is missing as after the change I restarted network.services 
and got IPv6 RA errors.  So I rebooted and now no eth0 listed with 
ifconfig (or ip addr show).  So something is lacking.  Almost like udev 
is not running at boot?  How do I check this out?
