Thank you for responding Ryan. 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:
