  19 #
  20 # Initial setup of a fai server on debian. works on localhost.
  21 # Set's the current ip as the tftp server. I vaguely remember
  22 # that using a hostname does not work.
  23 # Separate from running this, faiserver needs to be setup in dns
  24 # to point to whatever host this is run on.

 126 # http://askubuntu.com/questions/3503/best-way-to-cache-apt-downloads-on-a-lan

 128 # It touts having minimal dependencies, but I don't care.

 130 # you have to add all the repos you use.
