Systemd is an init systemd that makes use of rc?.d links, as it uses that information to determine if a service without native unit is enabled. > (As a > random possibility, installing sysvinit or similar could trigger the > generation of rc?.d scripts, avoiding the need to generate them at > install time.

Unfortunately, invoke-rc.d relies on the enablement links as well. Thus update-rc.d must happen before invoke-rc.d. Converting invoke-rc.d to triggers is not as trivial, as not all scripts have to be started on package installation/upgrade, and restart-on-upgrade behavior differs. -- Saludos, Felipe Sateler
