=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.

    Tons of new stuff, major rewrite of most of the

    core apps, tons of new apps as noted in header files.

    Lots of tedious effort writing these boring docs that

    nobody is going to actually read.
