5.4 LIBC NSS
GNU Libc 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. BusyBox has made it Policy that it will never use NSS, and will never use and libc
calls that make use of NSS. This allows you to run an embedded system without the need for
installing an /etc/nsswitch.conf file and without and /lib/libnss_* libraries installed.
If you are using a system that is using a remote LDAP server for authentication via GNU libc
NSS, and you want to use BusyBox, then you will need to adjust the BusyBox source. Chances
are though, that if you have enough space to install of that stuff on your system, then you
probably want the full GNU utilities.
