|
|---|
| 4 |
|
|---|
| 5 | GNU Libc (glibc) uses the Name Service Switch (NSS) to configure the behavior
|
|---|
| 6 | of the C library for the local environment, and to configure how it reads
|
|---|
| 7 | system data, such as passwords and group information. This is implemented
|
|---|
| 8 | using 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
|
|---|
| 10 | use of NSS. Some applets however, such as login and su, will use libc functions
|
|---|
| 11 | that require NSS.
|
|---|
| 12 |
|
|---|
| 13 | If you enable CONFIG_USE_BB_PWD_GRP, BusyBox will use internal functions to
|
|---|
| 14 | directly access the /etc/passwd, /etc/group, and /etc/shadow files without
|
|---|
| 15 | using NSS. This may allow you to run your system without the need for
|
|---|
| 16 | installing any of the NSS configuration files and libraries.
|
|---|
| 17 |
|
|---|
| 18 | When used with glibc, the BusyBox 'networking' applets will similarly require
|
|---|
| 19 | that 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 |
|
|---|
| 22 | Shameless Plug: As an alternative, one could use a C library such as uClibc. In
|
|---|
| 23 | addition to making your system significantly smaller, uClibc does not require the
|
|---|
| 24 | use of any NSS support files or libraries.
