Sorry I am not sure what exactly you mean here. I try to list packages that
might be relevant:

ii  init-system-helpers          1.65.2devuan1 all          helper tools for all init systems
ii  initscripts                  3.05-6devuan1 all          scripts for initializing and shutting down the system
ii  orphan-sysvinit-scripts      0.11          all          Orphaned System-V-like init scripts
ii  sysvinit                     3.05-6devuan1 amd64        System-V-like init utilities - transitional package
ii  sysvinit-core                3.05-6devuan1 amd64        System-V-like init
ii  sysvinit-utils               3.05-6devuan1 amd64        System-V-like utilities
ii  systemctl-service-shim 0.0.4-1      all          Adds systemctl translator script
ii  dummy-systemd-dev   0.2          all          Development files extracted from systemd

"systemctl-service-shim" might be what you are asking for, but I did not see
any alternative?

root@<host>:~# update-rc.d rsyslog enable
update-rc.d rsyslog enable
update-rc.d rsyslog enable
