+          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
+          initramfs statistic.
+
+          Otherwise, choose Y.
