Odd situation: I've mentioned before that I have several users for whom I have to spoof the MAC address, due to a software license. Now, I've got net.ifnames=0 biosdevname=0 on the grub2 command line, and I've got the spoofed MAC address in /etc/sysconfig/network-sctipts/ifcfg-eth0.
But he had a serious problem - X froze, and he thought to reboot, rather than call me. It came up with the actual MAC. I tried a number of things, including reboots, but the only thing that worked was systemctl stop NetworkManager, ifdown eth0, then ifup eth0, then start NetworkMangler, and all was good.
Yeah, I know, afterwards, I remembered I should have use nmcli....
But the real question is *why* did it fail on the reboot. I find no clues in dmesg, or messages, or boot.log.
Clues for the poor?

Is this box fully updated? I ask as the NM since 7.3 has different behaviour from release due to rebasing.
What does `nmcli con sh eth0 | grep clone` tell you?
It's that property you need to set.
