hi Alan:
Finally, I find the problem for my busybox NFS.
When using NFS with busybox, I have add one 'console' nod under busybox
/dev directory. And set the console with 666 attribute. If I do not set* 666
*attribute, NFS will NOT work with V3 NFS.
So now, busybox can be mounted by NFS successfully and even there is
some problem with Android boot, but I know it may none of business with NFS.
I will review my android building process and check the built binary...
Thank you very much!
