AFAIK, I don't have both systemd-networkd and NetworkManager "running" or enabled. In fact, I have had NetworkManager disabled on these systems for some time (back through F27, I believe). Post upgrade (or fresh install) I ensure that NetworkManager is not re-enabled, and that systemd-networkd is enabled. Unforuntately, trying to remove NetworkManager completely seems like a heavy hammer based on the `dnf remove` output below. Also, these identical systemd-networkd configurations do work on F30, just not on systems upgraded to F31. The only recent change I notice in F31, is that NetworkManager is initialized during early boot even when the service is disabled and masked. This is the early boot NetworkManager output: <info> [1573262139.2398] NetworkManager (version 1.20.4-1.fc31) is starting...
