And it looks screwed up inside the files, too, reject=no for no-bitmaps
and accept=no for yes-bitmaps:

# cat /etc/fonts/conf.d/70-no-bitmaps.conf
<?xml version="1.0"?>
<!DOCTYPE fontconfig SYSTEM "urn:fontconfig:fonts.dtd">
<fontconfig>
   <description>Reject bitmap fonts</description>
<!-- Reject bitmap fonts -->
  <selectfont>
   <rejectfont>
    <pattern>
      <patelt name="outline"><bool>false</bool></patelt>
    </pattern>
   </rejectfont>
  </selectfont>
</fontconfig>

# cat /etc/fonts/conf.d/70-yes-bitmaps.conf
<?xml version="1.0"?>
<!DOCTYPE fontconfig SYSTEM "urn:fontconfig:fonts.dtd">
<fontconfig>
   <description>Accept bitmap fonts</description>
<!-- Accept bitmap fonts -->
  <selectfont>
   <acceptfont>
    <pattern>
      <patelt name="outline"><bool>false</bool></patelt>
    </pattern>
   </acceptfont>
  </selectfont>
</fontconfig>
