Dalton Hubble	d77343be3a	Workaround systemd 248 path units not working reliably * On FCOS 34 / systemd 248, `kubelet.path` won't activate (stuck waiting) when `/etc/kubernetes/kubeconfig` exists, even with manual prodding of the file. The root cause isn't known, but a workaround is to delay `/etc/kubernetes` directory creation or to touch the directory later * Fix DigitalOcean worker node kubelet.service being enabled immediately. On bare-metal and DigitalOcean, the kubeconfig should activate the Kubelet, so it doesn't crashloop needlessly (nice to have, not required)	2021-06-16 10:19:39 -07:00
