+# password and group functions. Assuming you use GNU libc, when this is
+# `true', you will need to install the /etc/nsswitch.conf configuration file
+# and the required libnss_* libraries. This generally makes your embedded
+# system quite a bit larger... If you leave this off, busybox will directly
+# use the /etc/password, /etc/group files (and your system will be smaller, and
+# I will get fewer emails asking about how glibc NSS works). Enabling this adds
+# just 1.4k to the binary size (which is a _lot_ less then glibc NSS costs),
