  Bruce, I am of course using the same OS on each machine. Actually I am
  using the wonderfull FreeBSD netboot system to build a diskless client
  system. Since I have no local UFS filesystems its really hard to get a
  working /dev directory. The machine still have a hard drive and I would
  like to put some swap space on it. Hope this makes things clearer.
