奇怪的挂载点

home_king

在第五章的sources目录下载完所有软件包后，重新启动，发现了很奇怪的问题。

1. 
   
2. [root@localhost root]# mkreiserfs /dev/hda12
   
3.

24. The Defense Advanced Research Projects Agency (DARPA) is the primary sponsor of
    
25. Reiser4. DARPA does not endorse this project; it merely sponsors it.
    
26. 
    
27. Continuing core development of version 3 is mostly paid for by Hans Reiser from
    
28. money made selling licenses in addition to the GPL to companies who don't want
    
29. it known that they use ReiserFS as a foundation for their proprietary product.
    
30. And my lawyer asked 'People pay you money for this?'.  Yup.  Hee Hee.  Life is
    
31. good.  If you buy ReiserFS, you can focus on your value add rather than
    
32. reinventing an entire FS.  You should buy some free software too....
    
33. 
    
34. SuSE pays for continuing work on journaling for version 3, and paid for much of
    
35. the previous version 3 work.  Reiserfs integration in their distro is
    
36. consistently solid.
    
37. 
    
38. MP3.com paid for initial journaling development.
    
39. 
    
40. Bigstorage.com contributes to our general fund every month, and has done so for
    
41. quite a long time.
    
42. 
    
43. Thanks to all of those sponsors, including the secret ones.  Without you, Hans
    
44. would still have that day job, and the merry band of hackers would be missing
    
45. quite a few....
    
46. 
    
47. Have fun.

没有挂载上实际分区的挂载点居然会有目录结构！
请tram老大帮忙。

home_king

在此之前，用fdisk删掉一个分区/dev/hda12，然后又创建了一个相同大小的分区/dev/hda12，保存退出。正常地，fdisk提示设备忙，建议重启以update分区表。但是我没有这样做，直接mkreiserfs这个分区，直到第五章下载完所有源码包后重启就出现了上述问题。
估计是分区表冲突造成的问题。但具体原因还请各位兄弟及tram老大解疑。

如果没挂上，那目录结构就是在根分区里的啰?你是不是这种情况?

不是啊，和我的根分区无关啊。我是照提示另创建一个新分区来挂载$LFS的。
呵呵，tram老大，这么晚还未睡吗？
