+         In Linux, kernel has a special filesystem, rootfs, which is initially
+         mounted on /. It contains initramfs data, if kernel is configured
+         to have one. Usually, another file system is mounted over / early
+         in boot process, and therefore most tools which manipulate
+         mount table, such as df, will skip rootfs entry.
+
+         However, some systems do not mount anything on /.
+         If you need to configure busybox for one of these systems,
+         you may find useful to turn this option off to make df show
