Not that I know of, and yes there's the old folklore about Pine or some 
such old mail reader utilising it...

But other than as a 'nicety', why is "atime" there? What use has it?

I'm already using reltime as a 'nicety'.

... Just wondering if there is some common practice for backups and 
backups-verify that is simpler than remounting things "ro". "relatime" 
will still get updated when you do a verify of a file older than 24 hours.


Also, (OK, ultimate laziness here!): Is nodirtime needed in addition to 
noatime to avoid disk writes for just reading a directory? (The "man 
mount" page doesn't say...)

Cheers,
Martin
