Falling back to unversioned `/etc/fonts/conf.d` when versioned one does not exist is problematic since it only occurs on non-NixOS systems and those are likely to have a different version of fontconfig. When those versions use incompatible elements in the config, apps using fontconfig will crash. Instead, we are now falling back to the in-package `fonts.conf` file that loads both the versioned global `conf.d` directory and the in-package `conf.d` since using upstream settings on non-NixOS is preferable to not being able to use apps there. In fact, we would not even need to link `fonts.conf`, as the in-package `fonts.conf` will be always used unless someone creates the global one manually (the option is still retained if one wants to write a custom NixOS module and to avoid unnecessary stat call on NixOS). Additionally, since the `fonts.conf` will always load `conf.d` from the package, we no longer need to install them to sytem `/etc` in the module. This needed some mucking with `50-user.conf` which disables configs in user directories (a good thing IMO, NixOS module will turn it back on) but otherwise, it is cleaner. The files are still prioritized by their name, regardless of their location. See https://github.com/NixOS/nixpkgs/pull/73795#issuecomment-634370125 for more information.

Subject: [PATCH] add check for /etc/fonts/@configVersion@/fonts.conf
|
|
|
|
It's checked between FONTCONFIG_FILE and the in-package etc/fonts/fonts.conf.
|
|
The latter is used so that on non-NixOS distributions, fontconfig works at least
|
|
with upstream defaults, even when the global config is incompatible.
