To check the rootfs_data filesystem, mount_root will mount the filesystem to a temporary location (/tmp/overlay), check the file /tmp/overlay/etc/config/fstab, which is the same fstab configured above, for a configured extroot. If found, it will search in order /tmp/overlay/upper/sbin/block, /tmp/overlay/sbin/block, and /sbin/block for the presence of the block binary, and if it finds one will run that binary with the extroot argument.
