Content-Type: text/plain; charset=us-ascii; format=flowed Content-Transfer-Encoding: 7bit Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org I'm doing some work where it would simplify things greatly to have copy-on-write semantics available. I've seen overlayfs and the proposed "-union" option for mount, but there doesn't seem to be anything thats really ready for serious use. Am I missing something? Is someone working on this?
