    liangxiao:

    1. Have you uncompressed the file system onto the Linux host machine at the

        same location given in your bootargs?

        /home/user/workdir/filesys

    2.  Have you exported that directory on the Linux host side, making it a shared directory?

         On my Ubuntu 10.04 Linux host I would add this by:

         sudo gedit /etc/exports

        Add the following line to this file:

        /home/user/workdir/filesys *(rw,nohide,insecure,no_subtree_check,async,no_root_squash)

     3.  Restart the nfs server to make changes take effect. 

          sudo /etc/init.d/nfs-kernel-server restart.

    NOTE:

    Commands required for steps 2 and 3 depend on which Linux distribution you are using

    Ubuntu, Red Hat, etc.
