The question is which apps.

I usually mount filesystems noatime but the caveat has always been,
"watchout some apps require it".  I think this has reached the point of
being unix folk-lore.

I've asked many Sysadmins to name a single app that misbehaves if
filesystems are mounted noatime and (as far as I recall) no one has yet
presented a credible example.  This isn't criticism of the claim, just a
genuine request.

Can anyone name an application which misbehaves or breaks if filesystems
it relies on are mounted noatime?

This is somewhat OT I know, but while we're talking about it...
