为什么 'NetworkManager-wait-online.service' 启动失败并带有错误 'code=exited, status=2/INVALIDARGUMENT' ?

Issue

• 在 team 接口上的 VLAN 被配置为使用 nmcli。 当服务器重启时，它会在启动 NetworkManager 服务时挂起并失败，显示以下错误。

• 如果设置了 NM_CONTROLLED=no，则不会发生相同的问题。
• 在将内核升级到最新的 RHEL 7.3 版本的 kernel-3.10.0-514.2.2.el7 后开始出现这个问题，使用较旧的 kernel-3.10.0-327.el7 引导系统不会发现这个问题，系统可以正常引导。
