关于系统启动的问题

[watermelonyu]

一台B2000机器，昨天晚上我正常关机后，今天早上开机时，我连接网络一直连接不上去。后来我用串口线连上一看，发现主机在启动操作系统的服务时报如下附件中的错误。必须要配置网络机器才能启动，不然又回到BCH界面下去了。

>> 在我配置网络后(没有配置网卡的IP地址)，进入系统中发现如下怪的现象：1。原本/etc/hosts文件里面与主机名和IP对应的行不见了。2。查看/etc/rc.config.d/netconf文件，发现里面少了许多内容，如下附件所示。3。查看/etc/rc.log文件发现里面的启动项正常。 4。查看网卡的状态也是正常的。 5。查看文件系统的状态也是正常的。

>> 后来我又重启系统，除了可以启动到系统后，其余现象一样。

>> 请你们帮助我解决这个问题。先谢谢了!
