insserv looks at the dependencies specified in the LSB header and then
generates symlinks in /etc/rc?.d/ including a start priority.

The priority is not used by systemd, only the information if a service
is enabled or not. The start order is determined by systemd itself by
looking at the LSB header of sysv init scripts and native unit files and
then generating a dependency graph dynamically during boot.
