Commands service and systemctl.

[peter]

Hi,

https://en.wikipedia.org/wiki/Systemd has many occurrences of
"service", none referring to the service command.

For several somethings, the result of command,
service something COMMAND
approximates the result of
systemctl COMMAND something.service
although systemctl might be more powerful.

Does the relationship between service and systemctl parallel that
between ifconfig and ip? service is a legacy command?

Thx,              ... P.
