This is a tangent but you seem to be under the impression that filesystems grow on trees. I&#x27;ve been waiting for a modern COW linux filesystem for almost a decade now. Maybe in a few years it&#x27;s mature enough to wait a few more years for it to become stable? (I&#x27;m looking at you BTRFS) ;)<p>I guess BTRFS would fall into the filesystems that do everything category... Though at the other side of the spectrum you have filesystems that have not been tested enough or isn&#x27;t maintained.
