+            If you leave this disabled, busybox will use the system's shadow
+            password handling functions.  And if you are using the GNU C library
+            (glibc), you will then need to install the /etc/nsswitch.conf
+            configuration file and the required /lib/libnss_* libraries in
+            order for the shadow password functions to work.  This generally
+            makes your embedded system quite a bit larger.
+
+            Enabling this option will cause busybox to directly access the
+            system's /etc/shadow file when handling shadow passwords.  This
+            makes your system smaller and I will get fewer emails asking about
+            how glibc NSS works).  When this option is enabled, you will not be
+            able to use PAM to access shadow passwords from remote LDAP
+            password servers and whatnot.
