获取 ansible os 家族和 ansible pkg mgr 与设置

我们可以通过设置模块和过滤器的 Ad-Hoc 命令获取事实（ansible_os_family，ansible_pkg_mgr）。

• ansible_os_family：

    $ ansible all -m setup -a 'filter=ansible_os_family'
    ra.local | SUCCESS => {
        "ansible_facts": {
            "ansible_os_family": "Debian"
        },
        "changed": false
    }
  

• ansible_pkg_mgr：

    $ ansible all -m setup -a 'filter=ansible_pkg_mgr'
    debian.local | SUCCESS => {
        "ansible_facts": {
            "ansible_pkg_mgr": "apt"
        },
        "changed": false
    }
