Thanks for your answer! One question though - in case I remove ifupdown, what will happen to scripts installed by postfix, bind and other services ? Actually, the question is not what will happen to the scripts but will the fact that these scripts are unavailable disturb the services ? Or how to migrate services to systemd-networkd (if needed) ?

@golder3, I have no idea what business postfix could have installing ifupdown scripts, but they will be ignored if you are using systemd-networkd instead.

In my case, after an update of Ubunto to 18.04+, I also had ifupdown scripts by postfix in /etc/network, but still switched to networkd, which ignore these scripts, and, thus far it works. It would be nice to know that indeed postfix does not use these scripts in 18.04+ and they are only leftover from the previous release.
