Ubuntu10.10网卡配置文件重启失效

 　　环境：ubuntu 10.10,　　目标：配置网卡启动时加载iptables规则,　　网络上搜到的各种操作：,　　sh -c "iptables-save > /etc/iptables.rules",　　vi /etc/network/interfaces,　　## 目标网卡下增加一条命令,　　## pre-up iptables-restore < /etc/iptables.rules,　　但是，经测试发现。重启后这些配置会丢失，查看这个文件头会发现。,　　# This configuration file is auto-generated.,　　# WARNING: Do not edit this file, your changes will be lost.,　　# Please create/edit /etc/network/interfaces.head and /etc/network/interfaces.tail instead,,　　# their contents will be inserted at the beginning and at the end,　　# of this file, respectively.,　　#,　　# NOTE: it is NOT guaranteed that the contents of /etc/network/interfaces.tail,　　# will be at the very end of this file.,　　文件写得很明确，/etc/network/interfaces是自动生成的。如果我们需要自定义配置，那就创建/etc/network/interfaces.head或/etc/network/interfaces.tail。其中/etc/network/interfaces.tail并不推荐。,　　以下是一个示例：,　　auto venet0:0,　　iface venet0:0 inet static,　　address 184.22.224.125,　　netmask 255.255.255.0,　　pre-up iptables-restore < /etc/iptables.rules,
