Comment 15 for bug 1649931

systemd-networkd-resolvconf-update.service uses default dependencies which will only run after sysinit.target, however cloud-init.service needs to run before sysinit.target; systemd apparently dropped running the service due to the inconsistent order. Adding a DefaultDependencies=no to systemd-networkd-resolvconf-update.{service,path} allows cloud-init.service to run early with DNS before sysinit.target.

I've marked verification failed for this bug since the current proposed packages do not resolv the issue without changes to systemd package (/lib/systemd/system/systemd-networkd-resolvconf-update.{service,path}.
