Oh. Sorry. Totaly forgot its name.
When I hear "ubiquity" I am thinking "ubiquiti",
the wireless antenae manufacturer.

I did try to create "initrd.img" and "vmlinuz" from the VM machine 
I created (ubuntu workstation v12.04 LTS, x86). The actual 
machine has upgraded to kernel v3.2-0-98-generic, so I tried 
to create the two files :

mkinitramfs -o ./initrd.img (for the initrd.img file)
and
cp /boot/vmlinuz-`uname -r` ./vmlinuz (for the kernel)

Both files created fine.
Did a backup copy of the existing files (just in case)
Put the new files there 
Re-booted one of the thin-clients and the system never boots;
As if the NFS share cannot read the two files . . . .

Yep. That's what I did. Double-checked and triple-checked
with my documentation. Obviously I am doing something 
wrong, however as far as I can tell, I've done everything 
according to the documentation.

Any ideas ? I am completely stuck.

Also, tried this on both installations/clients' sites. Same thing.
The system does not go past the os choice during boot-up.
