NO for two reasons:
- atime semantics are just fine in server environments
- inotify IS NOT scalable to millions of files, nor
to situations where we want to check alteration weeks
or months after the fact

In reality I would perhaps prefer mount-behaviour being altered
from 'by default do atime' to 'by default do noatime.

There MUST be an easy way to tell system that "yes, I want to track
last accesstime."

I did recently an embedded Linux PC system where the entire
system disk is a single Compact Flash -card. I tried to play
with noatime option, but the system still kept writing things,
and thus I had to do full and somewhat drastic read-only.
