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