附加多个结构化的定制事实

Question

我试图将多个结构化的custom facts附加到我的根密钥（这里称为rag）上，但是它们总是替换当前值。

问题1：这是Facter.add的预期行为吗？

因此，要使其正常工作，我创建了两个external facts，然后在custom fact上读取它们的结果，并使用type => :aggregate附加到根目录中

我确实得到了预期的结果，

：〜＃事实-p rag

{
  role => "win-mbox",
  ambiente => "producao",
  enabled_services => [
    "auditd",
    "lvm2-monitor",
    "mdmonitor",
    "rhsmcertd",
    "rsyslog",
    "sshd",
    "syslog",
    "sysstat",
  ]
}

为了更好的维护，我将其分为多个文件（每个脚本输出1键），但是我觉得应该有更好的方法。

问题2：还有更好的方法吗？我的意思是，不必仅使用自定义事实来读取外部事实值并附加。
