Yes, looks like it:
root@scrooge:/# ls -la /run/systemd/system/
total 0
drwxr-xr-x 2 root root 40 May 8 02:50
. drwxr-xr-x 6 root root
180 May 8 02:50 ..

Doesn't look like I have that:
root@scrooge:/# ls -la /var/run/
total 4
drwxr-xr-x 4 root root 80 May 8 02:50 .
drwxr-xr-x 20 root root 4096 May 8 02:50 ..
drwxrwxrwt 2 root root 40 May 8 02:50 lock
drwxr-xr-x 6 root root 180 May 8 02:50 systemd

dbus is installed, however it is not running. In fact I think systemd
hasn't actually started anything.

I suspect systemd might be trying to display something on the console,
however I am not sure how to display that stuff using openvz/proxmox
(thought there was a way...)
I think systemd has got into a very strange state, where it thinks it has
started, but it isn't really running properly, and as such hasn't started
anything it was suppose to.
Also, not just systemd that can trigger this problem (also: does the
following really mean hplip and colord can't be installed without systemd?)

You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
colord : Depends: policykit-1 (>= 0.103) but it is not going to be
installed
init : PreDepends: systemd-sysv but it is not going to be installed or
sysvinit-core but it is not going to be installed or
upstart but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or
specify a solution).
In this case following the recommended advice reinstalls systemd, which was
kind of the opposite direction of what I was hoping for...
At some stage I will need to upgrade the kernel on this box, that will
support systemd properly (according to other reports), however will wait
and see if you need any more information on first.
