<div dir="ltr">My knowledge is somewhat limited to the Linux world, but in my experience I've never seen a mount be set to 'ro' and have anything updated. I hate to use the term 'flabbergasted', but I'm pretty sure that if I saw an implementation that didn't respect the 'ro' flag, I'd be at the very least 'put out', and perhaps even vitriolic. <div>

Hi folks. I encountered something odd.<br>
<br>
Suppose you mount a file system read only. You read a file from it. Does<br>
the access time of that file get updated?<br>
<br>
In one place I found documentation saying no. But other places seem to<br>
imply that it does.<br>
<br>
Does the answer change if it is an NFS mount?<br>
<br>
I have deliberately left details of what OS I'm using out, because it<br>
seems to me that the answer should be consistent, and if it is not, it<br>
should be documented publicly.<br>
