I have read previously that you can't use "eth*" as the device name. As an experiment, you could try using a device name other than "eth0" and see if that works.

OK.  But that is what the default is on the F20 remix.

This is on a f20 arm system, but it should be like any F20 system. Yeah,
famous last words.

So I want a 70-persistent-net.rules so I can specify the MAC address to
the device name.  Then in the ifcfg-xxxx I can change the MACADDR to
what I want.

I got this working on my Redsleeve arm system, but now I need it on my
F20 arm system.

So I have done a little searching on creating 70-persistent-net.rules,
and I come up with two commands:

udevadm trigger
udevadm trigger --action="">
I have run both and no 70-persistent-net.rules

help please...

As before, you need to create it yourself. I wrote a little script that will do this, which you can see here:

https://alteeve.ca/w/Changing_Ethernet_Device_Names_in_EL7_and_Fedora_15%2B#Writing_The_udev_Rules_File

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="" 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?
