Another thing I thought I'd mention, you don't have to do it for an entire filesystem. You can use chattr +A /path/to/file and it will just not record atime for that file ( or files ). Nice if you want to play around and see what type of impact it will have on your system without having to remount your filesystem. --------------------------------- Frank Wiles <[EMAIL PROTECTED]> http://www.wiles.org ---------------------------------
