=head1 LIBC NSS

GNU Libc (glibc) uses the Name Service Switch (NSS) to configure the behavior
of the C library for the local environment, and to configure how it reads
system data, such as passwords and group information.  This is implemented
using an /etc/nsswitch.conf configuration file, and using one or more of the
/lib/libnss_* libraries.  BusyBox tries to avoid using any libc calls that make
use of NSS.  Some applets however, such as login and su, will use libc functions
that require NSS.

If you enable CONFIG_USE_BB_PWD_GRP, BusyBox will use internal functions to
directly access the /etc/passwd, /etc/group, and /etc/shadow files without
using NSS.  This may allow you to run your system without the need for
installing any of the NSS configuration files and libraries.

When used with glibc, the BusyBox 'networking' applets will similarly require
that you install at least some of the glibc NSS stuff (in particular,
/etc/nsswitch.conf, /lib/libnss_dns*, /lib/libnss_files*, and /lib/libresolv*).

Shameless Plug: As an alternative, one could use a C library such as uClibc.  In
addition to making your system significantly smaller, uClibc does not require the
use of any NSS support files or libraries.
