However, users, such as myself :), can be interested in when a certain file has been last accessed. With snapshots I can even get an idea of all the times the file has been accessed. > *And go KISS and move on faster* better? Well, it in uncertain to me if it truly is better that btrfs would after that point no longer truly even support atime, if using it results in blowing up snapshot sizes. They might at that point even consider just using LVM2 snapshots (shudder) ;). -- _____________________________________________________________________ / __// /__ ____ __ http://www.modeemi.fi/~flux/\ \ / /_ / // // /\ \/ / \ / /_/ /_/ \___/ /_/\_\@modeemi.fi \/
