I agree with that reasoning. In any case, I think that the btrfs clone operation should be disallowed in ecryptfs as a matter of urgency (upstream as well), since it can result in data loss, which is far worse than the (presumably small in practice) disk space savings available though using the clone. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1305335 Title: Cutting or copying files on btrfs to ecryptfs results in data loss To manage notifications about this bug go to: https://bugs.launchpad.net/ecryptfs/+bug/1305335/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
