Comment 1 for bug 1549366

You can actually already deploy Tempest using a package:

class { '::tempest':
  install_from_source => false,
  tempest_config_file => 'where/you/want',
}

And in your manifest:

package { 'openstack-tempest':
  ensure => present,
}
Package['openstack-tempest'] -> Class['::tempest']

Not sure this is a bug or please add more context.
