There were two problems with this command. First, we needed to copy the
etc/kayobe directory instead of just etc, to avoid generating an extra
layer of kayobe directories. Second, its behavior was different
depending on whether the target directory already existed or not:
instead, copying files under etc/kayobe always produces a predictable
result.
