autoload Mosquitto MQTT

Help and Support Help
1

Good day.
Help add Mosquitto to startup (autoload).
I try the commands:
root @ volumio: / home / volumio # enable mosquitto service
bash: enable: mosquitto: not a shell builtin
bash: enable: service: not a shell builtin
Been so.
root @ volumio: / home / volumio # systemctl enable mosquitto.service
Synchronizing state for mosquitto.service with sysvinit using update-rc.d …
Executing /usr/sbin/update-rc.d mosquitto defaults
Executing /usr/sbin/update-rc.d mosquitto enable

I don’t understand very well in teams, what am I doing wrong?

It might help if you could explain in a few words for which project you intend to use this message broker and more important, on which sbc platform.
Volumio is not a general purpose OS, so it is possible that things are missing you need which we did not seem necessary for our audio platform.
