重启登录前提示：

Code:

network interface eth0 does not exist
please verify hardware or kernel module (deriver)
error: cannot start netmount as net.eth0 could not start

#ifconfig
只有 lo 项
#ifconfig -a
只有 lo 和 dummy0 两项

#lspci 可以检查出网卡

说明：系统装好后第一次编译的系统网络是通的，后来重新编译了一次内核（没动过网络部分选项），结果重启后两个内核都出现这样错误。。

从新编译了内核，把网络网卡相关的选项都编进内核，还把大部分网卡驱动也编进去，新内核OK _________________ 熟练内核配置是基本功!

恭喜恭喜!

不过, 我建议你进一步研究一下: 自己的网卡是什么, 真正起作用的驱动模块是哪个. 然后进一步精简.

步骤很简单:

$ /usr/sbin/lspci | grep -i ethernet - 你将会看到自己的模块的型号
然后拿着这个型号去 google, 加上 "linux driver/module" 之类的关键字, 你会得到一些信息
$ lsmod, 你会看到中间有某个模块和上一步搜索的结果有关联, 那就是我们要的模块了
重新编译内核, 把其他没必要的驱动都弄掉, 完美.
