Boot a full Linux system and gain complete control over your device WITHOUT modifying the firmware.
Depthboot is a builder script that creates a bootable USB drive/SD-card that can be booted on any x86_64 Chromebook. It supports common Linux distributions(Pop!_OS, Ubuntu, Arch and Fedora) and a variety of the most popular desktop environments. Due to licensing restraints, Depthboot cannot be distributed as an iso. Instead, it has to be build locally.
Pretty cool project, haven't seen it before. as someone who has used two different UEFI flashed Chromebooks as main laptops it's not something I would use. Really only useful if you want to retain ChromeOS compatibility and I guess only want Linux as secondary option.
