[BBLISA] Does read only really mean it?

[Alex Aminoff]

Hi folks. I encountered something odd.

Suppose you mount a file system read only. You read a file from it. Does 
the access time of that file get updated?

In one place I found documentation saying no. But other places seem to 
imply that it does.

Does the answer change if it is an NFS mount?

I have deliberately left details of what OS I'm using out, because it 
seems to me that the answer should be consistent, and if it is not, it 
should be documented publicly.
