This bug was fixed in the package systemd - 222-2ubuntu1

---------------
systemd (222-2ubuntu1) wily; urgency=medium

  * Merge with Debian unstable. Remaining Ubuntu changes:
    - Hack to support system-image read-only /etc, and modify files in
      /etc/writable/ instead.
    - Keep our much simpler udev maintainer scripts (all platforms must
      support udev, no debconf).
    - initramfs init-bottom: If LVM is installed, settle udev,
      otherwise we get missing LV symlinks. Workaround for LP #1185394.
    - Add debian/udev.lvm2.init: Dummy SysV init script to satisfy insserv
      dependencies to "lvm2" which is handled with udev rules in Ubuntu.
    - Add debian/udev.lvm2.service to avoid running the dummy lvm2 init
      script.
    - Provide shutdown fallback for upstart. (LP: #1370329)
    - debian/extra/ifup@.service: Additionally run for "auto" class. We don't
      really support "allow-hotplug" in Ubuntu at the moment, so we need to
      deal with "auto" devices appearing after "/etc/init.d/networking start"
      already ran. (LP: #1374521) Also run ifup in the background during boot,
      to avoid blocking network.target. (LP: #1425376)
    - ifup@.service: Drop dependency on networking.service (i. e.
      /etc/init.d/networking), and merely ensure that /run/network exists.
      This avoids unnecessary dependencies/waiting during boot and dependency
      cycles if hooks wait for other interfaces to come up (like ifenslave
      with bonding interfaces). (LP: #1414544)
    - Add Get-RTC-is-in-local-time-setting-from-etc-default-rc.patch: In
      Ubuntu we currently keep the setting whether the RTC is in local or UTC
      time in /etc/default/rcS "UTC=yes|no", instead of /etc/adjtime.
      (LP: #1377258)
    - Put session scopes into all cgroup controllers. This makes unprivileged
      user LXC containers work under systemd. (LP: #1346734)
    - systemctl: Don't forward telinit u to upstart. This works around
      upstart's Restart() always reexec'ing /sbin/init on Restart(), even if
      that changes to point to systemd during the upgrade. This avoids running
      systemd during a dist-upgrade. (LP: #1430479)
    - Drop hwdb-update dependency from udev-trigger.service, which got
      introduced in v219-stable. This causes udev and plymouth to start too
      late and isn't really needed in Ubuntu yet as we don't support stateless
      systems yet and handle hwdb.bin updates through dpkg triggers. This can
      be dropped again with initramfs-tools 0.117.
    - Lower Breaks: to plymouth version which has the udev inotify fix in
      Ubuntu.
    - Lower apparmor Breaks: to the Ubuntu version that dropped $remote_fs.
    - Change systemd-sysv's conflicts to upstart-sysv. (LP: #1422681)

    Upgrade fixes, keep until 16.04 LTS release:
    - systemd Conflicts/Replaces/Provides systemd-services.
    - Remove obsolete systemd-logind upstart job.
    - Clean up obsolete /etc/udev/rules.d/README.
    - systemd.postinst: Migrate mountall specific fstab options to standard
      util-linux "nofail" option.

  * ifup@.service: Run ifup for "auto" class in ExecStart instead of
    ExecStartPost, as it spawns a long-running dhclient daemon which we can
    only do in ExecStart. (LP: #1466790)

systemd (222-3) UNRELEASED; urgency=medium

  * systemd/udev postinst: Avoid "The group [...] already exists as a system
    group. Exiting." warnings. (LP: #1475094)

systemd (222-2) unstable; urgency=medium

  [ Adam Conrad ]
  * debian/udev-udeb.install: Install new bits for net.ifnames (LP: #1473542)
  * debian/extra/initramfs-tools/hooks/udev: Do the same for initramfs-tools.

  [ Martin Pitt ]
  * emergency.service: Wait for plymouth to shut down. Fixes invisible
    emergency shell with plymouth running endlessly. (LP: #1471258)
  * Add "networkd" autopkgtest. Covers basic DHCP on IPv4 and IPv4+6 on a veth
    device.

  [ Michael Biebl ]
  * Bump package priorities of systemd and systemd-sysv to important to match
    what has been used in the Debian archive since Jessie.
  * Drop scsi_wait_scan hack from the udev initramfs-tools script. This Linux
    kernel module has been broken since 2.6.30 and as a result was removed in
    3.5. The Debian Jessie kernel no longer ships this module.
    (Closes: #752775)
  * Drop libsystemd-journald-dev and libsystemd-id128-dev. There are no
    reverse dependencies left and we want to avoid new packages picking up
    a build dependency on those obsolete transitional packages.
