I have a dream:), I want to customize an "ubuntu-11.04-alternate-amd64.iso" image. What is the best software/solution for it?

I want to customize these things (ALL OF THEM is needed):

• Customized package list: I don't need all that comes with the default install, but I have a few thats not inc. in the def. install.

  
  



• GUI: I don't want a Desktop Environment in it, I only want to use the Openbox WM.

  
  



• I want a "half-automated" install: the installer only asks for: 1 encryption password + timezone + 1 username/password.

  
  

  So e.g.: the installer automatically creates an encrypted VolumeGroup with the given password (partitions: 256 MB /boot + VG get's the rest of the place: in the VG: 10 GByte to / and 2 GByte to swap and the rest goes to /home). - I mean with full encryption.

  
  



• Automatically configure a few apps: e.g.: Google Chrome/Firefox - e.g.: auto install WOT+NoScript in them.

  
  



• Automatically install & configure: grsecurity; PaX; Pro Police; DigSig.

  
  



• Configure in a way that the OS will do all the updates automatically without user interaction.

  
  



• Set file associations, e.g.: VLC for all the video files, etc.

  
  



• Install a Local DNS cache + Privoxy proxy & configure them to use as default, e.g.: ns: 127.0.0.1, HTTP/S proxy: 127.0.0.1:8118

  
  



• Automatically set the iptables Firewall rules that I provide.

  
  

Thanks for any help reaching my goal. Have a nice day.

p.s.: All that in one ISO image file (so not like e.g.: boot from a PXE server, i need a custom image in my hand that already contains the needed packages(even extra pack.) not that it downloads them when installing :P )
