  You have convinced me in that I have to review how FAI works; I've never
  used it and only took a look at it a long time ago, but with your comments
  I'm sure I want to review it; if what you say is true I'm sure that the
  proposed CDD Tool and FAI can be used together simply making FAI input files
  another output format for the CDD description.

  I only have started to work on the CDDTool and my initial idea is to have a
  common CDD definition format and a parsing tool for it that can generate
  different output files, that should be fast to do, but real life issues have
  slowed down the initial development. Anyway I'm working on it and I'll try
  to have something soon to start playing.

  As I've said many times, I don't want to duplicate effort and in fact my
  CDDTool proposal was done while trying to use existing tools to build a CDD,
  the idea is to reuse as much as possible and learn from others; now I know
  that FAI is another knowledge source and I will use it.

  Well, the idea is to have a debian-installer output for the CDD description,
  once we know that it works we can try to integrate CDD support into the
  debian-installer, but right now is easier to use it as is.

  Well, this list and the people involved is interested in working together
  and with Debian, I don't see any problem with that, maybe the only one is
  the lack of time.
