/etc/rc.conf used first to satisfy dynamic linking
if /etc/ld.so.conf (or /usr/local/etc/ld.so.conf whichever is chosen)
exits, then its contents override /etc/rc.conf for each library found
in the directories listed.

example:
/etc/rc.conf: /usr/lib
        /usr/lib contains libc.so.2.2
                          libc.so.3.0
/etc/ld.so.conf: /usr/local/lib
        /usr/local/contains libc.so.3.0

then any programs that require libc.so.3.0,
use the one in /usr/local/lib

any programs that require libc.so.2.2
use the one in /usr/lib
 
any vendor can install their own library to override the default
no one has to rewrite their files unless they choose to populate
/etc/ld.so.conf
