Comment 4 for bug 980835

So, while don't have a strong opinion on if group read is a problem, it seems that if getty is going to allow looser permissions than the default udev rule, (ie adding group read), it should be an active decision to solve a real problem. Before the permissions were more strict, so from a security point of view, it wasn't a problem. Perhaps we should adjust util-linux to use 0620 to mimic the udev rule?
