The reason we don't update kernel and rootfs because the size of kernel and rootfs is too large, it is hard to download 60MB image OTA via 4G CAT M1. If we are going to change to use 4G CAT1 or higher speed, I'll use either RAUC or SWUpdate, which one is the most popular for embedded system using uboot and UBFIS?
You don't need a full download. In the past I've used binary diffs with great success.
So if the update size is your biggest concern, the tradeoff of computing and applying the binary diff might be worth it.
