pi-display/blinkt/display-led.py : move from crontab to ? systemd ?

[BradleyA]

Thinking about moving the services to containers (Thinking not just off the top of my head; the container will create an security risk because of the need for --privileged) or systemd. (systemctl status docker.service ; journalctl -xe )

Full container capabilities (--privileged)

The --privileged flag gives all capabilities to the container, and it also lifts all the limitations enforced by the device cgroup controller. In other words, the container can then do almost everything that the host can do. This flag exists to allow special use-cases, like running Docker within Docker.
