Install CD source code

Hello, I want to create a custom CD to install Kubuntu. Where do I get the source code of the softwares used by Kubuntu Alternate CD?

How custom? Most customisation can be done via remastersys or similar.

Many tools such as Remastersys and UCK work only with live CD instead of alternate CD. These tools can create a CD with all data that is stored in the computer, and it can not be used to install Kubuntu to different computers for different users.

I want to edit a CD, I want to add and remove packages, remove other languages, add all packages for my language, add repositories, and finally, run a bash script after everything be installed and configure specific details. I want to simplify the instalation steps.

You don't need the source code to do that. You will need to modify the packages and package lists, and burn the finished product to a bootable CD.

The source code is for each individual application, having it won't let you add and remove things, only edit the applications themselves.

The source code that I am looking for is the source of the software that is used to install Ubuntu. This software is run when we boot an Alternate CD to install Ubuntu. I could edit it to simplify installation questions with custom default answers. I want the source to understand better how Ubuntu works and how it is installed.
