Title:
  AttributeError: module 'curtin.util' has no attribute 'RunInChroot'

Status in curtin:
  Fix Released
Status in curtin package in Ubuntu:
  Fix Released
Status in curtin source package in Xenial:
  Fix Released

Bug description:
  [Impact]

   * Curtin removed a previously used python module method,
     'RunInChroot' which was used by non-ubuntu curthooks for 
     deploying OSes like CentOS.  Removing the method prevents
     deploying CentOS where it worked prior to updating.

     Curtin has been updated to include an alias to the previous method that
     provides backward compat to callers of 'RunInChroot'
     
  [Test Case]

   * Install proposed curtin package and deploy CentOS to target system

    PASS: CentOS deploys successfully.

    FAIL: CentOS deployment fails with message:

    AttributeError: module 'curtin.util' has no attribute 'RunInChroot'

  [Regression Potential]

   * Other OSes besides CentOS may have used other flags against
     the original 'RunInChroot' method which is not being tested and
     may fail with the backward compat mode supporting 'RunInChroot'.


  [Original Description]
  I tested curtin bzr418 and bzr415, and I get the following error. This is a regression provided that it is not backward compatible and will cause all CentOS deployments via MAAS to fail.

  MAAS injects curtin_hooks code to CentOS images that call such
  function. If users upgrade to the latest curtin, they wont be able to
  deploy CentOS.
