I have written a little bash script once that takes an Arch Linux ISO and generates a new ISO with a modified root image which does a fully automated install. This includes partitioning as well as setting up and configuring the system with Xorg, FVWM, and Chromium. The installed system will login automatically and start Chromium. Just put the new ISO on a USB flash drive and lean back. ;-)
Disclaimer: the script is provided as-is, no warranty given. I haven’t used it in a while, so it might need a tweak here or there. Modify as needed.
