+config BUSYBOX_CONFIG_USE_BB_PWD_GRP
+ bool "Use internal password and group functions rather than system functions"
+ default n
+ help
+ If you leave this disabled, busybox will use the system's password
+ and group 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 password and group 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/password, /etc/group files (and your system will be
+ 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 remote LDAP password servers and whatnot. And if you
+ want hostname resolution to work with glibc, you still need the
+ /lib/libnss_* libraries.
+
+ If you enable this option, it will add about 1.5k to busybox.
