Title:
  On trusty I can break out of pivot_root chroot

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  After doing a pivot_root, it should not be possible to use the
  standard well-known 'chroot escape' technique to escape back to the
  host root.  However, Andrey Vagin found that on 14.04 that is in fact
  possible, if you first chroot.

  In 14.10, this is NOT possible.

  I've uploaded testscripts under
  http://people.canonical.com/~serge/chrootintoslave .  Download the
  cis.* from there into a home directory in a clean vm, make them all
  executable, and run "./cis.maintest".

  I posted a similar set of scripts (just tweaking how the chroot+chdir
  are done after pivot_root) in
  http://people.canonical.com/~serge/chrootintoslave.2 - those have the
  same results on my system.
