Since its initial +introduction, this feature was called “remote bootstrap”, but Todd pointed out +that this naming caused some confusion with the other “bootstrap” term used to +describe the process by which a tablet loads itself at startup.</p> + + <p>The discussion concluded with an agreement to rename the process to “Tablet Copy”. +Todd provided patches to perform this rename, which were committed at the end of the +week last week.</p> + </li> + <li> + <p>Congratulations to Attila Bukor for his first commit to Kudu!
