Okay, I got the exact same result.
If you're finding that everything is "in use" then at this stage it's
probable that you've made a filesystem backup with tar or cpio, which
obviously reads every single file, unfortunately making atime useless.
I use dump and restore test (I know some files will change and be
inconsistent, but that is okay). I plan to use lvm snapshots soon to
make sure everything is 100% consistent.
Don't use tar or cpio for backups.
I also use rsync for backups to other areas and remotely, so that might
update atimes? I don't think it should.
