I will just inform about the status. Everything is fine now. A word
about systemd-networkd-wait-online: With this service running there
has been even a delay of 1-2 seconds when switching from one console

idea about that side effect.
Does it happen each time or it is getty startup time? In the latter case
you may try (for various console numbers)
systemd-analyze critical-chain [email protected]
Now I have disabled systemd-networkd-wait-online and I have add a
comment in the last line of /usr/lib/systemd/system//systemd-networkd.service
which is now
# 28.2.2023 Also=systemd-networkd-wait-online.service
Ideally the root cause of strange behavior should be debugged. Perhaps
some dependency should be removed from e.g. multi-user.target or
network-online.target. Probably "systemd-analyze critical-chain" may
give some hints.
Any case I would not touch files in /usr/lib/systemd. It should confuse
tools like systemd-delta. It is possible to override specific properties
by creating of drop-in snippets in
/etc/systemd/system/systemd-networkd.service.d/. See systemd.unit(5),
e.g. run
systemctl edit systemd-networkd.service
[Install]
# Clear
Also=
# Add other values from the original file
Also=systemd-networkd.socket
Check result
systemd-analyze verify systemd-networkd.service
I hope, it is a better way to apply your workaround. I can not suggest a
better solution for tty delay issue, but I think it exists. "Also="
should affect "systemctl enable systemd-networkd.service" and "disable"
commands, so I puzzled why it helps at all.
