Description of problem:
In /etc/fonts/fonts.conf on "Font directory list" one can find:
... <dir>/usr/share/X11/fonts/OTF</dir> ...
but there is no such directory on a system. OTOH we have
/usr/share/X11/fonts/TTF and which is not on that list although
/usr/share/X11/fonts/Type1 does show up.
Is all of that correct and/or desired? Confused!
Version-Release number of selected component (if applicable):
/usr/share/X11/fonts/OTF will be there if you install xorg-x11-fonts-syriac.
