網路卡啟動錯誤解決方法，
在重啟網路卡的過程中出現如下錯誤：
shell# /etc/init.d/networking restart
* Reconfiguring network interfaces...
eth0: ERROR while getting interface flags: No such device
SIOCSIFADDR: No such device
eth0: ERROR while getting interface flags: No such device
SIOCSIFNETMASK: No such device
SIOCSIFBRDADDR: No such device
eth0: ERROR while getting interface flags: No such device
eth0: ERROR while getting interface flags: No such device
Failed to bring up eth0.
解決辦法：
刪除配置規則快取檔案，重啟後會根據現在的網路配置重新生成，然後重啟
shell# rm -rf etc/udev/rules.d/70-persistent-net.rules
shell# reboot
重啟後會發現網路卡正常啟動
