systemd 220(released in 2015) supports the "--now" switch.
When this switch is present, the units that are enabled will also be started, and the ones disabled also stopped.
This is a good opportunity to remove some unnecessary lines of code and improve code readability.
We can start and stop services with just one single command:
Also, systemctl daemon-reload is not really necessary when disabling/enabling a service.
Let me know if you notice any unintended side effects or if you have any feedback in general!
