Because people doesn't want to see creating a file under /usr/share/fonts say on host. that's the most concerns/complaints I've ever seen and this way may looks negative approach like returning to the old behavior where we had created cache files under /usr in the past I guess. Hmm, I totally missed the point that flatpaks can have own fonts in the container under /usr/share/fonts where the host fonts is installed and could be different. indded mapping font directories may not help in this case. For another idea that satisfies not creating a file under /usr, can flatpak rebuild symlinks at the startup time? That is to represent mapping between UUID (or the unique value if it doesn't like) and dir to a symlink. The directory structure looks like at host: /path/to/fontconfig/caches/on/host/ \___<unique value>-le64.cache-7 /path/to/fontconfig/dirs/on/host/: \___<unique value>.dir -> /usr/share/fonts/foo At the container: /run/host/fonts-cache/ \___<unique value>-le64.cache-7 /run/host/fonts-dirs/ or somewhere else: \___<unique value>.dir -> /run/host/fonts/foo So fontconfig can knows where it is from symlink instead of the location of .uuid file. look at the filename of symlink to access cache. then can open caches against it or update as needed. flatpaks just needs to create symlinks with the same filename but to the proper paths. it can be used instead of <dir> elements in config file perhaps. Eventually fontconfig should drops the hardcoded paths in cache and need to change API too to get the real path for current env. this can be the plan for next major release, fontconfig 3 in the future, but anyway. > > [1] https://github.com/debarshiray/fedora-toolbox > _______________________________________________ > Fontconfig mailing list > Fontconfig@xxxxxxxxxxxxxxxxxxxxx > https://lists.freedesktop.org/mailman/listinfo/fontconfig -- Akira TAGOH _______________________________________________ Fontconfig mailing list Fontconfig@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/fontconfig
