Ignore all that. There is an issue but I'm blaming the wrong thing.

Title:
  cron starts twice

Status in cron package in Ubuntu:
  Invalid

Bug description:
  A fresh Ubuntu 16.04 server install...

  cron starts twice every boot. It has been running for a while but I
  have made no changes to cron since the fresh install, other than
  installing some crontabs.

  The first cron show systemd as its parent.
  The second cron shows Upstart as its parent.

  To work around I have disable the Upstart process:
  $ sudo update-rc.d cron disable

  This results in some jobs running around 30 times, I assume due to
  some sort of race condition between the two crons.
