Warning: As Brunch is not the intended way for ChromeOS to work, at some point a ChromeOS script could potentially behave badly with Brunch and delete data unexpectedly (even on non-ChromeOS partitions). To do so, it uses a 1GB ROOTC partition (containing a custom kernel, an initramfs, the swtpm binaries, userspace patches and config files) and a specific EFI partition to boot from it. The purpose of the Brunch framework is to create a generic x86_64 ChromeOS image from an official recovery image.
First of all, thanks goes to project Croissant, the swtpm maintainer and the Chromebrew framework for their work which was actively used when creating this project.
