  1. =head1 LIBC NSS
  2. GNU Libc (glibc) uses the Name Service Switch (NSS) to configure the behavior
  3. of the C library for the local environment, and to configure how it reads
  4. system data, such as passwords and group information. This is implemented
  5. using an /etc/nsswitch.conf configuration file, and using one or more of the
  6. /lib/libnss_* libraries. BusyBox tries to avoid using any libc calls that make
  7. use of NSS. Some applets however, such as login and su, will use libc functions
  8. that require NSS.
  9. If you enable CONFIG_USE_BB_PWD_GRP, BusyBox will use internal functions to
  10. directly access the /etc/passwd, /etc/group, and /etc/shadow files without
  11. using NSS. This may allow you to run your system without the need for
  12. installing any of the NSS configuration files and libraries.
  13. When used with glibc, the BusyBox 'networking' applets will similarly require
  14. that you install at least some of the glibc NSS stuff (in particular,
  15. /etc/nsswitch.conf, /lib/libnss_dns*, /lib/libnss_files*, and /lib/libresolv*).
  16. Shameless Plug: As an alternative, one could use a C library such as uClibc. In
  17. addition to making your system significantly smaller, uClibc does not require the
  18. use of any NSS support files or libraries.
