Whats the status of this. Can we come up with an agreed upon format
for doing the dir remapping (outside of the dir nodes) soon? I'm about
to do a flatpak 1.2 release and would like to preempt things by
generating the dir mapping dynamic snippet so we can use it when we
update fontconfig in the runtime. (Note: We need not yet finalize the
salt stuff, because that will not be in the dynamic flatpak-generated
part of this.)
