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? mark
