Hi Marco

 Thanx for the email. I've been debugging this problem for a few days and a
few installs before I posted the first email in this thread I started
sniffing the network interface on the server (dhcp, tftp, http are all on
the same computer) and I noticed that no communication reaches the server
between the PXE load and the retrieval error (and I think I wrote about it
in my original post). Some people suggested that it might be that Linux gets
confused in the interfaces (the Sun X2200 M2 has 4 NICs), which I find hard
to believe (Linux kernel is old enough and probably got rid of these kind of
bugs a long time ago). In some of the failures the kernel loaded, retrieved
the kickstart configuration file and than failed to retrieve 'stage2.img'
(again nothing appeared on the wire). I have a sneaky feeling that the
kickstart process assumes a lot of basic facts and doesn't do any/enough
sanity checking. Right now I need to get this cluster up and running (I'm
already 2 weeks behind schedule). After it's up I will try to debug the
process.
  The situation got me so aggravated that I was contemplating resurrecting
my old private distro (not going to do that) that does things in a much
simpler way.
