Most of the 6 hours was spent just trying to figure out why when I tried
to do it the dbootstrap way nothing was happening.  I tracked it down to
having to use "sid" instead of unstable, then I started to have
downloading problems, since the script starts fresh every time it was
wiping things and I changed that, which led to more isssues about
symlinks and other things later on.

Then I got into the config area and sort of just threw up my hands. 
What I need to see is basically a decision and action flow chart that
FAI takes for configuration.

I plan to fully understand the FAI system ... it's just too much that is
unknown to me at the moment.

What I am going to do at the moment is take the core of the FAI idea (at
least I think it's the core) and have systems mount the nfs-root that
will be the new system, partition with sfdisk from a file (they are all
identical so this is not an issue) make my raid drives, mount the target
and un-tar the sytem, changing the config files in just a few places.  

It's really just a matter of what I can do the fastest at this moment. 
Like I said initially, FAI seems to be what I want in the future, it's
just that the deadline came up too quickly and I'm more comfortable
working with something I understand completely.

For under 20 identical workstations once I have my shell script written
it should be mostly painless, though I still have to manually config
each box due to the network card issues so I'm already missing the put
in a floppy and go philosophy of FAI.  I actually hope to contribute to
the project in the near future once I can fully grok it.
