Title:
  System will not start with multipathd enabled

Status in multipath-tools package in Ubuntu:
  Fix Released
Status in multipath-tools source package in Xenial:
  Fix Committed

Bug description:
  [Impact]

   * Both systemd units and init scripts are shipped for multipath-
  tools.

   * However units did not correctly take priority, as initscripts and
  units names did not match.

   * Further more multipath-tools was miscompiled without systemd
  support for Type=Notify unit

  [Test Case]

   * Using service command, init script, or systemctl commands starting
  "multipath-tools" should operate on systemd "multipathd.service" unit.

   * Systems must boot with multipath-tools installed correctly, and
  multipathd.service started.

  
  If I do these three commands on a fresh Ubuntu clone which has one pair of FCP devices pointing to a LUN:

  # apt-get -y install multipath-tools
  # systemctl enable multipathd
  # reboot

  The system will not come back up. It seems to spin with the messages:
  “A start job is running for Device-M...vice Controller (<x> / 1min
  30s)”  In 90 seconds it times out and starts counting again.
