I've done implementation for salt: https://gitlab.freedesktop.org/tagoh/fontconfig/commits/flatpak-rework That should works as expected. For summary to support this on flatpak side, All of flatpaks needs to have: <dir salt="something">/usr/share/fonts</dir> and more if there are any fonts directories on sandbox where has same directory names on host. or may be better having a salt regardless of it to make them differenciated to host perhaps. I'll leave it to you, Alex. No salt should be needed for remap-dir so far. Ah, and if you want to manage fonts directories in a single file and don't want to modify fonts.conf, you can put <reset-dirs/> prior to re-define own fonts directories with dir elements. Please test it.
