what you are saying only is true fpr sysvinit-scripts but not for 
systemd-units when you have some clue what you are doing

that's why you place your own systemd units below /etc/systemd/system/ 
with the same name or use dropins

* disable service with "systemctl disable smb.service"
* place your modified copy at /etc/systemd/system/smb.service
* enable service with "systemctl enable smb.service"
* voila the symlink points to your unit and no longer
   to /usr/lib/systemd/system/smb.service
