That `tar -xvf containerd-1.2.0-rc.0.linux-amd64.tar.gz -C /bin` cleans out `/bin` before extracting on CentOS 7, leaving the system in a useless state (`ls`? Who needs `ls`?). Instead, this extracts the files and moves them to their new spot much like the other commands in this step.
cri-containerd project is moving as a sub-project of containerd itself;
the GitHub migration is complete. Also, as of 9 Jan, the beta.1 release
of cri-containerd is available so the download link is updated.
