I just switched our cluster to clustermatic, but did not
manage to get the first stage working properly ; so I went
for PXE/DHCP thanks to our EEpro100+, discovering that PXE is not needed
(you can send an image and bootdisk with DHCP only) ;
and using the autodiscover function in clustermatic
(or Scyld), I see the MAC addresses without having the hassle
of typing them....So now the nodes download the second stage directly
  with DHCP (no first stage anymore) and boot in about 15 s total.

By the way, with Scyld, bproc or clustermatic, there is no need
for NIS, remote linux install, passwd distribution, and so on.
