For the 8.04, all thin clients. the initramfs screen is shown on the clients
but the edubuntu desktop is shown on the server.

I will try doing this during the weekend. I reinstalled the 7.04 and did not
have any problems with 28 thin clients. The clients boot in just a few
seconds, very very fast. Will try with 34 day after next.

On the 8.04 that was what I did during the weekend (a few hours before a
super storm decided to change its path and crossed near our area). The
generic boots OK if that was selected as the boot. But I have reinstalled
the 7.04 so that the students will able to use the computers. Of course I
know the 8.04 is better.

Okay, I guess I could do this over the weekend when the computer laboratory
is all quiet. I am sorry I won't able to send the debug output as I have
done a re-installation of 7.04. I will try a redo this weekend.

Thanks for the help.
