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. + =head1 MAINTAINER Erik Andersen <andersen@codepoet.org> @@ -229,5 +252,5 @@ Tito Ragusa <farmatito@tiscali.it> =cut -# $Id: busybox_footer.pod,v 1.15 2004/04/06 17:52:02 andersen Exp $ +# $Id: busybox_footer.pod,v 1.16 2004/04/13 16:31:41 andersen Exp $ |
