Playing with this more, I think I see what you mean now. Indeed there
appear to be bugs.


Could you please take a look at all the systemd units and init scripts,
and how they intervene with each other?

* /etc/init.d/multipath-tools-boot
  - this one works fine

* /etc/init.d/multipath-tools
  - this one is enabled by default, and starts up without loading dm-multipath first

* /lib/systemd/system/multipathd.service
  - a trap, that is easy to shoot oneself in the foot.
  - has alias Alias=multipath-tools.service but doesn't appear to properly be enabled in maintainer scripts, and doesn't seem to be masking multipath-tools-boot initscript at all.
  - does not appear to be operational properly. 
  - references non-existant units
  - deamon fails to create socket... yet unit declares that socket activation is to be used.

Could you please dig further into these units and check what needs

  System will not start with multipathd enabled

Status in multipath-tools package in Ubuntu:
Status in multipath-tools source package in Xenial:

Bug description:
  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.
