Currently it supports only `service start <SERVICE>`, but it could grow e.g. `stop`, `exec` etc in the future (although you can still use `ctr` for those). In order to be able to use go-compile.sh the containerd build needs to move from /root/go to /go as the GOPATH. The vendoring situation is not ideal, but since this tool wants to be an exact match for the containerd it seems tollerable to reuse its vendoring.
