如果想在 netifrc 中使用 dhcp 动态获取 ip 的同时，添加自己需要的 dns server（例 如 127.0.0.1），该怎么办？

可以通过安装 dhcpcd 并且在 netifrc 中指定使用 dhcpcd 作为 dhcp client 获取 ip：

# emerge -av net-misc/dhcpcd
# vim /etc/config/net
    modules="dhcpcd"

然后创建一个 /etc/resolv.conf.head 文件，把自己需要的 dns server 填入：

# vim /etc/resolv.conf.head
    nameserver 127.0.0.1

也可以是 /etc/resolv.conf.tail 文件。 head 表示往 /etc/resolv.conf 头部插入 ，tail 表示往 /etc/resolv.conf 后部插入。

Thanks for reading :)
