Don't edit the unit file. Create a drop-in override file instead. The "systemctl edit" command will start that process for you. Or, if you like, you can manually create the appropriately named subdirectory under /etc/systemd/system/ and create a *.conf file inside it. Either way, the file should contain only the lines you need, which are just: [Install] WantedBy=rescue.target According to the man page (systemctl(1)), after doing an "edit", the configuration is automatically reloaded, so step 2 shouldn't be necessary, but it certainly won't hurt. I don't think step 3 is needed, or even desired. Maybe I'm wrong? I'm not inclined to test this right now, since it entails rebooting and is therefore highly disruptive.
