Finally, cfengine's convergence makes it possible to take a "blank" system and move it to a desired state, enabling quick stand-in replacements for crucial systems.
最后，cfengine的收敛使获得“空白”系统并使它达到期望的状态成为可能，并能够对关键系统进行快速临时替换。
In this case, instead of checking to see if the field was blank we could invoke a method on a model object to ensure that the current user wasn't already in the system.
在该例中，不是检查字段是否为空，我们可以调用模型对象的方法来确保当前用户已经不在系统中。
