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.
