[openbook] mysql password problem

During deployment puppet try set mysql password in:

deployment_scripts/puppet/modules/openbook/manifests/db/mysql.pp
  exec { 'mysql_root_password':
    subscribe => File['/root/.my.cnf'],
    require => Service['mysql'],
    path => '/bin:/sbin:/usr/bin:/usr/sbin',
    refreshonly => true,
    command => "mysql -u root --password='' < /root/.password"
  }

but it always set passsword for mysql as '' - missing variable

also in:
deployment_scripts/puppet/modules/openbook/manifests/params.pp
  $db_password = 'Tall!g3nt'

plugin always use default password during put data into mysql - dont care about real settings in UI
