I have a production environment built on aws using the latest template of dc/os 1.11. After I accidentally restart a node, this machine was unable to rejoin the cluster. I've checked the services on the current node and figured out some dcos services were failed like dcos-net.service and the systemd-timesyncd wasn't start spamming the following message:
`systemd-timesyncd.service: Job systemd-timesyncd.service/start failed with result 'dependency'`
How can I fix it and treat this issue to avoid future occurrences?
