Customizing D-I

An interesting opportunity appeared at work. I am going to make a custom D-I image.
It will involve:

• using a custom kernel,
• modifying the repo on the CD,
• using preseeding
• (probably) making a custom initrd.

This way I will probably get back in touch with D-I development ;-) .
Fun, fun fun. Doing Debian stuff at work, payed by my employer!
