"Fedora developers are looking at requiring all files that be placed in /usr world-readable. Developers are seeking a mandate that all Fedora packages must not install any non-world-readable files within /usr. Right now some Fedora packages do not honor this and restrict permissions to certain files/directories. Stakeholders are after making the user directory world-readable since containerized copies of Fedora can have the directory bind-mounted into the container, support for virtualization use-cases, and for better systemd handling.
