Does it work if you have the link only in the configured.d and off.d
directories? It would be nice to at least fix that comment in the
script if it's wrong.

It works.
If the configured state always appears later than the routable state, then this is probably the obvious solution.
I don't know if this is a possible situation, but if the AdministrativeState becomes configured first when the OperationalState is not routable, I think having the link file only in the configured and off directories will cause problems.

FYI, I've attached the logs for a couple of cases.
Each log contains all systemd-networkd events on the interface that occur during boot. (including dormant.d, no-carrier.d... etc.)
To the event that the 20-chrony script is called, I appended the source state immediately after the chronyc onoffline command was executed.

Does it work if you have the link only in the configured.d and off.d
directories? It would be nice to at least fix that comment in the
script if it's wrong.

I had a quick look at the systemd-network code, but wasn't able to
figure out how what is the state when applications can expect to be
able to make network connections.
