AFAIK, defragmentation is proportional to amount of writes to a file or direcotries. system files typically are installed once and never rewritten in place, so they should not be much fragmented to begin with. now their directory objects, is a different story and so is things like systemd journal, log files, or database files. -- Regards Shridhar -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
