I confirm that the image is bootable with your patch, thank you !!! As you said already, it lack the resize capability, which make the image somehow useless since it run out of space at first boot. I did try "resize_root=YES" in rc.conf without any luck.

I did end-up by using the live-image. The only missing piece for me was the "fstab_minwrites" (which is still relevant in 2022 seeing the price of CF card).
