Let's say the `SysV Init Script` is called foo (the file `/etc/init.d/foo`):

1. Start the service through Systemd: `systemctl start foo`
2. systemd-sysv-generator will generate this file `/run/systemd/generator.late/foo.service`, copy this file to `/etc/systemd/system` by running: `cp /run/systemd/generator.late/foo.service /etc/systemd/system/foo.service`
3. Edit `/etc/systemd/system/foo.service` by running `systemctl edit foo.service`, add in the following line to `foo.servie` (this makes the service installable)

   ```
   [Install]
   WantedBy=multi-user.target
   ```

4. Enable the server: `systemd enable foo.service`
