1=back 2 3=head1 LIBC NSS 4 5GNU Libc (glibc) uses the Name Service Switch (NSS) to configure the behavior 6of the C library for the local environment, and to configure how it reads 7system data, such as passwords and group information. This is implemented 8using an /etc/nsswitch.conf configuration file, and using one or more of the 9/lib/libnss_* libraries. BusyBox tries to avoid using any libc calls that make 10use of NSS. Some applets however, such as login and su, will use libc functions 11that require NSS. 12 13If you enable CONFIG_USE_BB_PWD_GRP, BusyBox will use internal functions to 14directly access the /etc/passwd, /etc/group, and /etc/shadow files without 15using NSS. This may allow you to run your system without the need for 16installing any of the NSS configuration files and libraries. 17 18When used with glibc, the BusyBox 'networking' applets will similarly require 19that you install at least some of the glibc NSS stuff (in particular, 20/etc/nsswitch.conf, /lib/libnss_dns*, /lib/libnss_files*, and /lib/libresolv*). 21 22Shameless Plug: As an alternative, one could use a C library such as uClibc. In 23addition to making your system significantly smaller, uClibc does not require the 24use of any NSS support files or libraries. 25 26=head1 MAINTAINER 27 28Denis Vlasenko <vda.linux@googlemail.com> 29 30=head1 AUTHORS 31 32The following people have contributed code to BusyBox whether they know it or 33not.
