Examples in Chef Provisioning 0.16.1 do not seem to work

destroy_all.rb

require 'chef/provisioning'

machine_batch do
  machines search(:node, '*:*').map { |n| n.name }
  action :destroy
end

knife.rb

# knife.rb used from http://chef.leopard.in.ua/
# This file exists mainly to ensure we don't pick up knife.rb from anywhere else
local_mode true
config_dir "#{File.expand_path('..', __FILE__)}/" # Wherefore art config_dir, chef?

# Chef 11.14 binds to "localhost", which interferes with port forwarding on IPv6 machines for some reason
begin
  chef_zero.host '127.0.0.1'
rescue
end
