Unnecessary text replacement?

[matthewpoer]

Can't tell if I'm missing some context or understanding. I don't think you need to do the sed text replacement for "SUBNET" against configs/kubelet-config.yaml

kubernetes-the-hard-way/docs/09-bootstrapping-kubernetes-workers.md

Lines 17 to 18 in 52eb26d

	sed "s|SUBNET|$SUBNET|g" \
	configs/kubelet-config.yaml > kubelet-config.yaml
