红帽全球峰会9.8. ipv6、netmask、gateway 和 hostname 内核参数已删除
从 RHEL 8.3 开始，在内核命令行中配置网络的 ipv6、netmask、gateway 和 hostname 内核参数不再提供。反之，使用接受不同格式的整合的 ip 参数，如下所示：
ip=IP_address:peer:gateway_IP_address:net_mask:host_name:interface_name:configuration_method
ip=IP_address:peer:gateway_IP_address:net_mask:host_name:interface_name:configuration_method
有关此参数接受的单个字段和其他格式的详情，请查看您系统上 dracut.cmdline (7) 手册页中 ip 参数的描述。
