Upgrading packages? 1st vm upgrades and copies changed files. After while second upgrades and copies files too. More and more becomes duped again. If you host multiple distributions you need to translate that /usr/share/bin/foo in foonux is /us/bin/bar in barux And primary reason to dedupe is not to reduce space usage but to improve caching. Why should machine A read file if machine B read it five minutes ago. > -- > 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 -- user to computer ration too low. -- 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
