Debian/Ubuntu basics

I want to load the Ubuntu 10.04 desktop CD contents into Cobbler Server so I can network-boot a PC from it and load it without interaction, like I do with CentOS and Fedora in Cobbler V2.0.11. I don't need updates or syncing of repos or anything. I've looked at wiki, bugs, forums, and am fairly confused. For CentOS/Fedora I used "import" but it doesn't work with --breed=ubuntu or debian. Some docs say to use "distro add" but that doesn't let you specify a --path, so how do I get the CD content into Cobbler with that? I thought maybe "repo add" would work but it doesn't seem to, it creates a repo entry but never copies the content of the CD.
