ChromeOS on Framework 13 11th DIY?

[ajb]

Hello to everybody,

I can confirm that ChromeOS runs very well on my new Framework Laptop 13 with AMD 7840U. For those who also want to play with ChromeOS, I am happy to provide my installation script. It runs just well on Fedora 39 as it does on Ubuntu.

script create-chromeos-image

#!/bin/sh -e
#
# creates a ChromeOS image for Framework Laptop 13 AMD 7840U
