Title:
  debugfs shouldn't be mounted by default

Status in systemd package in Ubuntu:
  Won't Fix

Bug description:
  On modern Ubuntu systems, /sys/kernel/debug is mounted by default due
  to sys-kernel-debug.mount being enabled by default.

  AFAIK, this FS doesn't need to be mounted for normal operations and
  back in the day, there were concerns about the security implications
  of having it enabled/mounted by default
  (https://lists.ubuntu.com/archives/kernel-
  team/2011-January/013418.html).

  Would it be possible to not have it mounted by default?
