Title:
  CFQ is default scheduler (incorrect udev rule)

Status in systemd package in Ubuntu:
  Invalid

Bug description:
  I've found out that all my drives uses CFQ scheduler by default, since
  that udev rule (60-ssd-scheduler.rules) that says use CFQ for rotating
  disk is useless. I belive that Ubuntu uses Deadline scheduler by
  default, but for somewhat reason it's not that on my system.
