Actually, I've got a concern about this feature.
I'm not sure what gnome-shell depends on for monitoring mdadm arrays,
but I know it will put up a notification if an mdadm member becomes
faulty; because I've seen this notification. Maybe it's getting this
information from udisksd? In any case, I'm wondering whether the user
will still be notified of device failures in gnome-shell with this
change?
