I think it's better to have the option than not have it, but for regular Joe user I think it's a problem. And that's why I'm not such a big fan of systemd-journald using chattr +C on journals when on Btrfs, by default. I wouldn't mind it if systemd also made /var/log/journal/ a subvolume, just like it automatically creates /var/lib/machines as as subvolume. That way by default /var/log/journal would be immune to snapshots. Or alternatively a rework of how journals are written to be more COW friendly. -- Chris Murphy -- 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
