How to add software and build a custom Ubuntu LiveCD

Have you have ever wished that the Ubuntu LiveCD came with different software packages, or had the ubuntu-restricted-extras (flash, mp3 support etc.) and b43-fwcutter (Broadcom wireless firmware/drivers) packages installed by default ?

You can easily create your own custom Ubuntu LiveCD using the Ubuntu Customization Kit (UCK).
