No /tmp/fai/, /tmp not writable

[John G Heim]

That did it.

In the past I used ch-boot to generate the pxe config files and then 
edited them manually. I thought I had to have anboth root and nfsroot 
parameters. I didn't understand the difference. Still don't actually. 
But I see that the root parameter is correct the way ch-boot generates 
it if you pass it the correct parameters.

So I kind of had to undo the edits I had made to the pxe boot file for 
my test machine. It wasn't quite right originally the way ch-boot 
generated it. But I think I can probably get it to do that if I pass it 
the right parms.
