Comment 5 for bug 1823396

Review 651754 on April 11 has nothing to do with this bug. It was for bug: 1824027

For this bug:
It looks as though the "$join_cmd" is cleared in hiera, therefore the puppet code raises an error.

To steps to "reinstall" are:
  system host-lock compute-0
  system host-reinstall compute-0

I am proceeding with those steps, to verify the bug.
