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