Speaking of Debian, that's what I use, there are quite a number of fonts files that are installed by
texlive-fonts-extra, e.g., the number of Open Type font files is
$ dpkg -L texlive-fonts-extra | grep otf | wc -l 1364 $
but these fonts are unknown to
$ dpkg -L texlive-fonts-extra | grep ComicNeue-Regular.otf /usr/share/texlive/texmf-dist/fonts/opentype/rozynski/comicneue/ComicNeue-Regular.otf $ fc-list ComicNeue $
I could copy/symlink some fonts to
~/.fonts/, but is it possible to instruct permanently
fontconfig to parse the fonts installed by TeX Live?
