I didn't know that the default had been changed to "relatime".  I can see the 
logic, of course.  There certainly is no harm in specifying "strictatime" (and 
it's cheap) for tmpfs.  You're right that tmpfs may get swapped, but I think 
the metadata would be the last thing to be forced out to swap, since it's very 
frequently updated.

Enjoy!

added [OT] to the subject.
