LFS-7.1安装笔记, 'devtmpfs filesystem问题'

asuerhao posted @ 2012年6月23日 01:19 in 积累 with tags LFS , 4687 阅读

    系统安装完成, 重启, 可是内核挂载虚拟文件系统‘/dev’时提示错误: 
’error unknown filesystem type devtmpfs‘.

    只好再次重启, 回到寄主系统中排查错误。看到文件/etc/fstab中有一行:
devtmpfs /dev devtmpfs mode=0755,nosuid 0 0
    内核在挂载这一文件系统时出错, google后才知道, 配置内核时还需要手动选择'devtmpfs filesystem'的支持:
Device Drivers --->
  Generic Driver Options --->
     Maintain a devtmpfs filesystem to mount at / dev
    重新编译内核, 重启, 问题解决.

    这似乎是在LFS-7.1中加入的新特性,不过手册中没有说清楚。

Some people may believe that this post contains simply a motivational information, but absolutely no... this article is really a call to use it. And lots of it. Also looked as "Massive action". I definitely don't wish to scare anybody away using the word "massive", but occasionally it's essential to provide a real possibility check. If you feel you're likely to see success within the cleaning through sticking the yellow web page ad search within the phone book for any good organization, good luck with this.
