We actually caught the ext4 size issue in the wild with the debug output in the oe_mkext234fs() code, but it did not help. What that showed was that the get_rootfs_size was returning a default size of 8192, where as the actual rootfs was more like 10572, thus too large to fit in the created sparse file.
This additional temporary debug code should help us determine where the failure might be.
