Yes, that what what I meant. There is also a Debian systemctl package, but it is
not really maintained and I wouldn't recommend it.
I notice you have dummy-systemd-dev installed. You really don't want that on a
production system. If is a hack for building sources that Build-Dep: systemd. It
doesn't provide any systemd functionality.
If you remove it does it make any difference?

Hmmm, I get completely different behaviour with that command:-
mark@apollo:~% sudo update-rc.d enable rsyslog
usage: update-rc.d [-f] <basename> remove
update-rc.d [-f] <basename> defaults
update-rc.d [-f] <basename> defaults-disabled
update-rc.d <basename> disable|enable [S|2|3|4|5]
-f: force
The disable|enable API is not stable and might change in the future.
What systemd-requiring package are you trying to install? What other changes
have you made?
