Title:
  chroot configuration strictly depends on overlayfs

Status in click package in Ubuntu:
  Fix Released
Status in click source package in Yakkety:
  Fix Committed
Status in click source package in Zesty:
  Fix Committed

Bug description:
  The kernel changed the module name from overlayfs to overlay, this
  needs to be taken into consideration when creating the chroot.

  [Impact]

  When trying to create the chroot, it fails like this:
  Processing triggers for sgml-base (1.26+nmu4ubuntu1) ...
  E: 10mount: mount: wrong fs type, bad option, bad superblock on click-ubuntu-sdk-14.04-armhf,
  E: 10mount:        missing codepage or helper program, or other error
  E: 10mount:
  E: 10mount:        In some cases useful info is found in syslog - try
  E: 10mount:        dmesg | tail or so.

  ERROR

  This makes the autopkgtests fail, so it's blocking bug #1693226.

  [Test Case]

  Run the click autopkgtests.
  Check that there are no errors related to the wrong fs type.

  [Regression Potential]

  Fixing this for artful could make it fail in previous versions.
  However, this was found by the autopkgtests, so as long as the chroot tests pass in the other revisions the fix is correct.

  [Other Info]

  Click is now longer in active development. These tests were failing
  for a long time. In here we are just trying to make a small change on
  the name of the python module so it doesn't conflict with
  python3-click which is in active development and needed by snapcraft
  in bug #1692102.
