+ Ignore rootfs entry in mount table.
+
+ 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.
