        "make install" will install "named" and the various BIND 9 libraries.
        By default, installation is into /usr/local, but this can be changed
        with the "--prefix" option when running "configure".
 
+       You may specify the option "--sysconfdir" to set the directory 
+       where configuration files like "named.conf" go by default,
+       and "--localstatedir" to set the default parent directory
+       of "run/named.pid".   For backwards compatibility with BIND 8,
+       --sysconfdir defaults to "/etc" and --localstatedir defaults to
+       "/var" if no --prefix option is given.  If there is a --prefix
+       option, sysconfdir defaults to "$prefix/etc" and localstatedir
+       defaults to "$prefix/var".

        If you're planning on making changes to the BIND 9 source, you
        should also "make depend".  If you're using Emacs, you might find
        "make tags" helpful.
