I've been looking at the DF installer this weekend and was wondering
what is the easiest way to create an unattended install of the OS?
Ideally, I'd like to be able to boot a CD and return some time later to
a completely installed and configured base system.
    
I haven't tried this, but it should be possible to put all installer
choices in a file called "pfi.conf" (for pre-flight installer) and place
it on a floppy or USB stick and have it proceed automatically.
Example fo the file here, I think:
http://cvs.bsdinstaller.org/cgi-bin/cvsweb.cgi/installer/root_skels/installer/etc/defaults/pfi.conf
  
Thanks!  Looking at this file, it appears to be a collection of options 
that affect the behavior and environment of the installer, which is a 
good start but doesn't seem to address the whole picture unless I'm 
missing something.  In other words, I want to be able to automatically 
create the file systems and all the other things that the installer 
presents during an interactive install as well.  Is this just a shell 
script that I need to create manually?  How do I get the installer to 
launch it?  Or am I approaching this from the wrong angle entirely?
