Yep, yep and yep for other sections, too. (will add my mods later) Maybe I missed something, but after I found hard-coded "mmcblkp04" in /boot/cmdline of Nemo image, I believe the problem is with that? Or maybe, as thinking while writing, I have added p7 to "kernels on them" section, maybe just replace? (i could not dig any deeper into code due to missing free time. It took me already two days to get here OK, with a lot of breaks )
