  27 Initial setup of a fai server on debian. works on localhost.
  28 Set's the current ip as the tftp server. I vaguely remember
  29 that using a hostname does not work.
  30 Separate from running this, faiserver needs to be setup in dns
  31 to point to whatever host this is run on.
  32
  33 For running on arm, it expects Ian's fai-basefiles repository at
