Seems like this is more confusing than necessary (as per usual).
This is part of the fonts.conf of my linux machine, so it is
probably not quite right for DFly:
<!-- Font directory list -->
<dir>/usr/share/fonts</dir>
<dir>/usr/local/share/fonts</dir>
<dir>/usr/X11R6/lib/X11/fonts</dir>
<dir>~/.fonts</dir>
If you have a fonts.conf in /etc/fonts you can try just making
a symlink to that file instead of writing a new one. Worth a
try, anyway. I'll try experimenting when I have more time.
Ok. Thank you.
