While this was my initial impression too, more careful reading made me
realize that the various methods they present really talk about having
the unattended file on the same media as the installer, not on a separate
one.
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=509723 seemed like it
could be useful for what we are trying to do, but I did not manage to
get it to work.

I didn't think about all of this in detail, but I agree that something less
cryptic than a string with magic !, @, ... would be good ;)
