I believe that this change has broken cosmic cloud-images. there is 'journalctl -o short-precise' output of a 20180530 image booted in kvm at http://paste.ubuntu.com/p/xhzxNc4QtR/
>From that you will see: May 31 15:54:35.838996 ubuntu systemd[1]: sysinit.target: Found ordering cycle on cloud-init.service/start May 31 15:54:35.839017 ubuntu systemd[1]: sysinit.target: Found dependency on systemd-networkd-wait-online.service/start May 31 15:54:35.839042 ubuntu systemd[1]: sysinit.target: Found dependency on systemd-networkd.service/start May 31 15:54:35.839064 ubuntu systemd[1]: sysinit.target: Found dependency on networkd-dispatcher.service/start The result is that cloud-init.service does not run as it needs to. ** Description changed: [Impact] networkd-dispatcher's systemd unit has default dependencies, which means it starts much, much too late to have any effect for interfaces brought up by networkd at boot (since the events are missed, and not replayed). We should instead have systemd unit dependencies like this (replicating systemd-networkd's own): [Unit] Description=Dispatcher daemon for systemd-networkd DefaultDependencies=no After=systemd-udevd.service network-pre.target systemd-sysusers.service systemd-sysctl.service Before=systemd-networkd.service In local testing, this DTRT. - [Test Case] + [Test Case] Start systemd-networkd / boot system with it, ensure networkd-dispatcher is started before it. + + Run 'journalctl -o short-precise | grep -i ordering'. There cannot be + any ordering cycles present. [Regression potential] Slower boots as systemd-networkd will now only run after networkd-dispatcher.service, and that runs after dbus.service. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1772137 Title: networkd-dispatcher starts too late to take effect on boot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/networkd-dispatcher/+bug/1772137/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
