Subject: dri/common: use sysconfdir when looking for drirc
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=c228514c72cb2fd5fb9e510808e29204fc9e7ae1;p=mesa.git

 <p>The DRI-enabled libGL uses expat to
-parse the DRI configuration files in <code>/etc/drirc</code> and
+parse the DRI configuration files in <code>${sysconfdir}/drirc</code> and
 <code>~/.drirc</code>. This option allows a specific expat installation
 to be used. For example, <code>--with-expat=/usr/local</code> will
