As pgf and dsd have thought, the problem lies in the ul-warning script

I tried to reproduce the problem w/ the following bash script but to no


  poweroff &
  while true; do chvt 3; done 

my bash skills are likely lacking

pgf and dsd probably could fix this eventually but the easiest way is to
simply disable the script so that the image is not displayed at
shutdown. We dont' have any legal reasons that compel us to display the
ul-warning so we are just going to remove it from our custom build.

Please let me know if removing ul-warning will cause any adverse effects
besides not displaying the ul-warning image.

tks again to pgf, dsd, quozl, and others who have helped
