pprindeville:

Currently it's hard-coded into /lib/preinit/79_move_config as:


move_config() {
	local partdev
. /lib/upgrade/common.sh

if export_bootdevice && export_partdevice partdev 1; then
	mkdir -p /boot
	if mount -t ext4 -o ro,noatime "/dev/$partdev" /boot; then
		if [ -f /boot/sysupgrade.tgz ]; then
			mount /boot -o remount,rw,noatime
			mv -f /boot/sysupgrade.tgz /
			mount /boot -o remount,ro,noatime
		fi
		mount --bind /boot/boot /boot
	fi
fi

}

that the first partition of the boot device is the boot partition. That's not always the case, and EFI seems to break this.

Also, it's an obstacle to supporting A/B image+config boot modes.
