It's a Qualcomm Snapdragon 7c Ver2.
I'm running the kernel that came with the image I downloaded from https://github.com/hexdump0815/imagebuilder a few months ago. I believe it's a 5.19.1 kernel minimally patched from kernel.org sources (and possibly some customization of the .config and devicetree). Reportedly, v6 of the kernel should work unpatched.
I should start a DebianOn page for the wiki.

Right, I get the general idea. Just not sure if you need to follow that process 100%, or if there's some flexibility. In particular, I don't know if the lz4 step is necessary, and whether other compression formats are allowed.
Relatedly, I'm wondering how many kernel partitions I can have. Can I have (usefully) a "KERN-Z" partition?

Is there anywhere (besides this list) that I should be reading/subscribed to to learn more about debian-installer support for Chromebooks?
