> The "default bionic install" uses only netplan yaml and /etc/systemd/network/ is empty.
yes, but netplan creates .network config files named in a deterministic way so you know what the name of the networkd file it creates will be. I don't think netplan currently has a mechanism to include keep- configuration options in the networkd config it creates. > Using '/etc/systemd/network/10-netplan-ens160.network.d/override.conf' with KeepConfiguration works perfectly the same. exactly, which is why you should use the drop-in instead of manually duplicating and editing the entire netplan-created .network config file, as you complained about when you said: > Now I need to have IP and gateway in two files since, no, you don't. Or, drop netplan and just directly configure systemd-networkd. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1815101 Title: [master] Restarting systemd-networkd breaks keepalived, heartbeat, corosync, pacemaker (interface aliases are restarted) To manage notifications about this bug go to: https://bugs.launchpad.net/netplan/+bug/1815101/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
