this is correct (and you were really fast, this was done a couple of hours ago!). I had done some doc updates, but you are right, that some pages were still referring to userdata. I have submitted 2 patches to fix the doc. thanks for your help! The 2 patches should be merged soon hopefully.
We have aligned the GPT scheme with the one we use on 410c. e.g. we have a “linux” GPT scheme where we expect users to flash the rootfs on the partition ‘rootfs’, and for this scheme we no longer have the various android partitions (cache, system, userdata, …).
We will create an Android GPT scheme (and so, an Android bootloader package) , in the coming weeks.
