systemd-sysctl.service complains "Failed to start Apply Kernel Variables"

[Po-Hsu Lin]

This issue was spotted on one of our server, during the upgrade process this message came up, I didn't know if there is anything that's not working due to this error, so far it looks good.

$ sudo systemctl status systemd-sysctl.service
