Looks like we get a good performance boost and only tmpwatch and mutt with mbox seems to be affected. A simple patch to tmpwatch has been posted on the same thread.
Thoughts on disabling it?
IMO, disabling atime by default, just because 99% of applications, don't use it, is short-sighted. It basically ditches a fundamental feature of unix filessystems and converts there behavior to "DOS'ish".
That said, I feel "noatime" might be suitable for selected partitions, but not as a general solution.
Also, I never understood what noatime solves what mounting partitions read-only can't do more properly.

Considering how easy it is for knowledgeable users to make disable atime, I don't see it as necessary to make this so by default.
