For x86 targets, increase the default rootfs size to 2048MB which allows online resizing the filesystem to up to 2TB which is the current theoretical maximum for LEDE, due to missing GPT support on the root block device. Note that the filesystem artefact will not occupy 2GB on the build system as the make_ext4fs utility uses sparse files to generate the filesystem images, so the actual disk usage is much lower. Furthermore the filesystem images are gzip compressed, shrinking them to only a few megabytes on the download server.
