The fact that /etc/daily updates the atime on all directories (I presume it's not actually all *files*, is it?) seems like a contributing poor behavior. That would mask any "actual" access time updates. It's too bad our open(2) doesn't have support for a O_NOATIME flag. With that, and modifications to fts(), find and locate's updatedb then you could keep atime turned on without as much of a daily performance hit. Eric
