Careful, that should make your system unbootable until the cmdline.txt is fixed.TimG wrote:For me the recipe still works with the updated official cmdline.txt patch file. It will fail if you forget the first line, which downloads the matching official cmdline.txt.
We switched to using PARTUUID in cmdline.txt and fstab instead of referring to the dev node. That will make the next image bootable from USB or SD. To do this, the cmdline.txt in pi-gen has a placeholder 'ROOTDEV' and 'BOOTDEV' which is replaced when the image is created. If you use that in your actual cmdline.txt the kernel won't know which filesystem to run init from.
