I recently read a blog post on customizing Ubuntu 9.04 (I believe) via the terminal. It explained how to download all the Linux base packages and create a Linux distro inside of a directory and then how to chroot that directory. Somewhere along the line I couldn't get a package to install that the tutorial needed so I had to drop the project altogether. I would like to continue with developing a distro but I can't seem to find the tutorial again and I've just purchased a brand new computer with all my files from my old one gone.
How would I go about downloading the base Linux files into a folder, chrooting that folder to install a few other programs, and then automatically starting a python script upon system boot (once the user has installed the system).
Thanks for all answers.
