DSM-G600, DNS-3xx and NSA-220 Hack Forum

Hello everyone,
I have been trying to move the /home folder on my Ubuntu desktop to the DNS-323 but haven't quite figured it out.  Has anyone else managed to do this successfully?

Here is what I have tried:

1. Mount DNS:
   1. $sudo gedit /etc/fstab  
    and add the line:
    dns.ip.address:/mnt/HD_a2 /media/DNS-323 nfs rw,auto 0 0
   2. $sudo mount -a
2. Make a new home directory
   1. $mkdir /media/DNS-323/home
3. Copy home folder
   1. $sudo find . -depth -print0 | sudo cpio --null --sparse --preserve-modification-time -pvd /media/DNS-323/home/
4. Move your existing home folder (note: make sure everything was moved cleanly before this step!!!!)
   1. $sudo mv /home /old_home

* Note: after this, the wallpaper disappears, indicating that Ubuntu can't find /home

5. Make a new “home” for /home:
   1. $sudo mkdir /home  
6. Modify your /etc/fstab file:
   1. $sudo gedit /etc/fstab  
    and add the line:
    dns.ip.address:/mnt/HD_a2/home /home nfs nodev,nosuid 0 2
   2. $sudo mount -a

* Note: after this, the wallpaper reappears, indicating that Ubuntu found the new /home on the DNS-323

At this point, I was patting myself on the back for a job well done.  Then the next time I booted up, I got a nasty error saying something about /home not being found.  To recover I booted in recovery mode then put /home & fstab back to original.

Any ideas as to what I may have done wrong?  Has anyone else been able to do this?
