(It's been several years since I was into embedded Linux systems.) https://elinux.org/images/0/02/Filesystem_Considerations_for_Embedded_Devices.pdf is focused on eMMC/SD Cards, which have built-in controllers that enable them to present a block device interface, which is very unlike what raw NAND devices have. Please see https://www.kernel.org/doc/html/latest/filesystems/ubifs.html for more info. Regards, Bjørn
