I actually don't remember anymore, why that wasn't sufficient.

So, the issue most likely is, that systemd is installed but not actually
the active PID 1, which means the systemd dependency alone is not
sufficient
"systemctl enable" should work, even when systemd is not PID 1,
apparently it doesn't do that (will investigate).

I think the auto-enabler in systemd should be sufficient, but if you want
to keep the current postinst, wrapping the systemctl call into a
if [ -e /sys/fs/cgroup/systemd ] ; then .. fi
should do the trick.
