I'd like to reduce the wear-and-tear on my SSDs and eliminate the 
unnecessary metadata writes on my backup media that only slow down the 
backup process. So I want to add noatime to all my mounts. Is there any 
downside to this?

At one time I remember atime being useful for tmpwatch, which removes files 
in /tmp that haven't been accessed in a week or two. But I can live without 
that feature.
