client install aborts

Very good Thomas, it is a "baby step" forward.

Well two issues simultaneously can be a bit of challenge?

First the black screen -- at this moment I expect to find a mis-match 
between my fai-client hardware and the software used to build the the 
client.  I'm confident the display is not the source -- I have done 
substitution without success.  That leaves the internal hardware -- and 
I can't do substitution there.  We will see how this gets resolved.

Second is grub -- at this moment when fai finishes the build and reboots 
[FYI this requires maybe 6 min], the fai-client seems to hang at reading 
MBR from hard drive.  Clearly fai is not doing a successful build, and 
the black screen is simply a nuisance at figuring out what went wrong.  
No -- there is not a client log on the server /var/log/fai directory 
either.

Well sorry to have stumped you.  There is one fact you might have 
missed? -- after the black screen fai  continues to build for another 
4-1/2 minutes before the fai-client automatically re-boots. NFS 
continues to deliver server content to the client that totals 79k 
packets.  The client hard drive remains active until reboot -- just like 
a normal build.  Even though the result is not 100% correct, fai is 
building something in the 5:50 min between power-on and re-boot.

I need to drag out a rescue OS to look inside fai-client to help with 
the next step?
Perhaps when I see what has been built it will make more sense.
