   8 config BUSYBOX_CONFIG_USE_BB_PWD_GRP

  10         default n
  11         help
  12             If you leave this disabled, busybox will use the system's password
  13             and group functions.  And if you are using the GNU C library
  14             (glibc), you will then need to install the /etc/nsswitch.conf
  15             configuration file and the required /lib/libnss_* libraries in
  16             order for the password and group functions to work.  This generally
  17             makes your embedded system quite a bit larger.
  18
  19             Enabling this option will cause busybox to directly access the
  20             system's /etc/password, /etc/group files (and your system will be
  21             smaller, and I will get fewer emails asking about how glibc NSS
  22             works).  When this option is enabled, you will not be able to use
  23             PAM to access remote LDAP password servers and whatnot.  And if you
  24             want hostname resolution to work with glibc, you still need the
  25             /lib/libnss_* libraries.
  26
  27             If you enable this option, it will add about 1.5k to busybox.
