Yes to both. I could imagine that for small systems/workstations
you might have some files that want access time, and others that
wanted NOATIME -- it seems the new flag lets you choose on a
file-by-file bases.

That's why I asked. I imagine it won't help on any well-administered
production server since they'd probably mount the whole filesystem
that way; but might help a bit on out-of-the-box-default-config
benchmarks done by naive users who don't tweak filesystem settings.

Don't know if we'd care about such an audience or not.
