  Ubuntu Core 16 images using cloud-init fail to function when the
  DataSource is over the network (Like OpenStack) as networking is not
  yet available when cloud-init.service runs.

(for xenial only) drop the useless org.freedesktop.network1.busname unit (which

systemd-network.service after sockets.target which is too late for cloud-init).

The resolvconf portion of this issue has been moved to bug #1649931.
I'm removing resolvconf 1.78ubuntu3 from xenial-proposed and will
replace it with a resolvconf 1.78ubuntu4 with the correct bug ref.

[Launchpad Bug Tracker]

This bug was fixed in the package systemd - 229-4ubuntu13

---
systemd (229-4ubuntu13) xenial; urgency=medium

  [ Martin Pitt ]
  * Backport graphical-session{,-pre}.target user units, for future usage from
snaps. (LP: #1640293)
  * debian/rules: Clean up *.busname units. They are useless in 16.04 as they
will always be "condition failed" as kdbus has never existed. But they add
ordering constraints which make it impossible to start
systemd-networkd.service during early boot, which is an upcoming
requirement for cloud-init. (Part of LP: #1636912)
  * Drop systemd-networkd's "After=dbus.service" ordering so that it can start
during early boot (for cloud-init.service). It will auto-connect to D-Bus
once it becomes available later, and transient (from DHCP) hostname and
timezone setting do not work in 16.04 anyway. (LP: #1636912)

  [ Dan Streetman ]
  * rules: introduce disk/by-id (wwid and model_serial) symlinks
for NVMe drives (LP: #1642903)

  [ Michael Biebl ]
  * Mark liblz4-tool build dependency as 
  * udev: Try mount -n -o move first
initramfs-tools is not actually using util-linux mount (yet), so making
mount -n --move the first alternative would trigger an error message if
users have built their initramfs without busybox support.

  [ Alexander Kurtz ]
  * debian/extra/kernel-install.d/85-initrd.install: Remove an unnecessary
variable. (Closes: #845977)

  [ Martin Pitt ]
  * Drop systemd-networkd's "After=dbus.service" ordering, so that it can
start during early boot (for cloud-init.service). It will auto-connect to
D-Bus once it becomes available later, and transient (from DHCP) hostname
and timezone setting do not currently work anyway. (LP: #1636912)
  * Run hwdb/parse_hwdb.py during package build.
  * Package libnss-systemd
  * Make libnss-* depend on the same systemd package version.

[Group.of.nepali.translators] [Bug 1636912] Re: systemd-networkd runs too late for cloud-init.service (net)

[Martin Pitt]

The "networkd after D-Bus" ordering was introduced in
https://github.com/systemd/systemd/commit/1346b1f038 and later refined
in https://github.com/systemd/systemd/commit/bcbca8291f .

So with the latter, removing this ordering would break the "UseHostname:
yes" flag (when you receive/set your host name from what DHCP gives
you), i. e. it would silently not work. We don't use that feature in the
distro itself, but it would be a shame to break it for everyone even
when cloud-init is not involved at all.

So this at least gives us a quick way out for 16.04 -- we can simply
drop the "After=dbus.service" from systemd-networkd.service without much
trouble, but for devel I'd at least discuss this with upstream.

Bug description:
  Ubuntu Core 16 images using cloud-init fail to function when the
  DataSource is over the network (Like OpenStack) as networking is not
  yet available when cloud-init.service runs.

  cloud-init service unit deps look like this:

  [Unit]
  Description=Initial cloud-init job (metadata service crawler)
  DefaultDependencies=no
  Wants=cloud-init-local.service
  Wants=local-fs.target
  Wants=sshd-keygen.service
  Wants=sshd.service
  After=cloud-init-local.service
  After=networking.service
  Requires=networking.service
  Before=basic.target
  Before=dbus.socket
  Before=network-online.target
  Before=sshd-keygen.service
  Before=sshd.service
  Before=systemd-user-sessions.service
  Conflicts=shutdown.target

  Here's networkd unit deps:

  [Unit]
  Description=Network Service
  Documentation=man:systemd-networkd.service(8)
  ConditionCapability=CAP_NET_ADMIN
  DefaultDependencies=no
  # dbus.service can be dropped once on kdbus, and systemd-udevd.service can be
  # dropped once tuntap is moved to netlink
  After=systemd-udevd.service dbus.service network-pre.target 
systemd-sysusers.service systemd-sysctl.service
  Before=network.target multi-user.target shutdown.target
  Conflicts=shutdown.target
  Wants=network.target

  # On kdbus systems we pull in the busname explicitly, because it
  # carries policy that allows the daemon to acquire its name.
  Wants=org.freedesktop.network1.busname
  After=org.freedesktop.network1.busname

  
  And a critical-chain output:

  root@snap-test7:~# systemd-analyze critical-chain systemd-networkd
  Failed to get ID: Unit name systemd-networkd is not valid.
  The time after the unit is active or started is printed after the "@" 
character.
  The time the unit takes to start is printed after the "+" character.
