=head1 LIBC NSS
|
|
|
|
GNU Libc (glibc) 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. This is implemented
|
|
using an /etc/nsswitch.conf configuration file, and using one or more of the
|
|
/lib/libnss_* libraries. BusyBox tries to avoid using any libc calls that make
|
|
use of NSS. Some applets however, such as login and su, will use libc functions
|
|
that require NSS.
|
|
|
|
If you enable CONFIG_USE_BB_PWD_GRP, BusyBox will use internal functions to
|
|
directly access the /etc/passwd, /etc/group, and /etc/shadow files without
|
|
using NSS. This may allow you to run your system without the need for
|
|
installing any of the NSS configuration files and libraries.
|
|
|
|
When used with glibc, the BusyBox 'networking' applets will similarly require
|
|
that you install at least some of the glibc NSS stuff (in particular,
|
|
/etc/nsswitch.conf, /lib/libnss_dns*, /lib/libnss_files*, and /lib/libresolv*).
|
|
|
|
Shameless Plug: As an alternative, one could use a C library such as uClibc. In
|
|
addition to making your system significantly smaller, uClibc does not require the
|
|
use of any NSS support files or libraries.
