This change adds a new --rootfs=path option to kubeadm, and (if
provided) chroot()s to this path before performing file operations.
This makes it possible to run the kubeadm binary from a container, but
perform remaining file operations against the host filesystem using
something like:
docker run -v /:/rootfs --net=host --uts=host --pid=host \
kubeadm:latest init --rootfs /rootfs...
Fixes kubernetes/kubeadm#503
