[tag:clone] and [tag:cloning] are used interchangeably, and largely in accordance with the description in the [tag:cloning] tag wiki.

I only spotted a handful of questions that didn't fit, and I retagged them:

 * Distributed version control: [1](https://askubuntu.com/questions/333343/git-cloning-error)
 * Multiple monitors: [1](https://askubuntu.com/questions/34083/clone-screen-default-projector) [2](https://askubuntu.com/questions/256012/no-sound-via-hdmi-and-i-cannot-use-mirror-display-on-a-lenovo-g560)
 * Users: [1](https://askubuntu.com/questions/196998/how-to-clone-root-user-in-ubuntu)


I prefer the name “cloning” since the questions are about the cloning activity, not about a clone. It's also the name [Unix & Linux](https://unix.stackexchange.com/) [uses](https://unix.stackexchange.com/tags/cloning). [Super User](https://superuser.com/) has both.
