Title:
  mounts are shared by default on ubuntu 15.04

Status in systemd package in Ubuntu:
  New

Bug description:
  Ubuntu 15.04:
      nir@reed:~$ grep '/ / ' /proc/self/mountinfo
      21 0 8:5 / / rw,relatime shared:1 - ext4 /dev/disk/by-uuid/70f9850c-8ebd-4881-a504-e14ec8d37f66 rw,discard,errors=remount-ro,data=ordered

  Ubuntu 14.10:
      nir@pilgrim:~$ grep '/ / ' /proc/self/mountinfo
      21 0 8:1 / / rw,relatime - ext4 /dev/disk/by-uuid/1d8ff8a8-6026-48dd-b6ce-e52b46c1f33d rw,errors=remount-ro,data=ordered

  This breaks CLONE_NEWNS and may present a security threat since
  process' private mounts are viewable to all and will persist after the
  process exits.
