Upstart issues with Ubuntu 14.04.

I believe Ubuntu is perhaps one of the lesser-used distros in GNHLUG
land, but I'm hoping someone here might be able to offer some insight.
I've got an Openstack install on Ubuntu 14.04 host systems, and after a
hurricane-induced power outage over the weekend, one of our hosts won't
boot -- it fails (seemingly) at loading an Openstack Neutron service.
So, I figure I'll go into /etc/init.d/ and just chmod -x all the suspect
services, see if it boots, and then manually load services. Not so
much; that had zero apparent impact on the services loading.
So then I did some reading up on Upstart, and found a whole bunch of
places that the services *might* be loading from... none of which seemed
to impact stuff. I currently have the host booted by some serious
cheating (I pulled a disk, went to "manual repair mode" when it whined
about not being able to mount devices, and loaded services from there --
it completely fails to boot single-user), but how in blazes do I:
* See what services want to be loaded?
* See *where* they get loaded?
* Load them individually?
I've found some of the services mentioned in /etc/init/, /etc/init.d/,
/etc/systemd/system/multi-user.target.wants/, /lib/systemd/system/,
/var/lib/systemd/deb-systemd-helper-enabled/ and
/var/lib/systemd/deb-systemd-helper-enabled/multi-user.target.wants/ .
I tried playing around with most (all?) of those locations, to no avail.
Any insight into what I'm doing wrong would truly be most appreciated.
Thanks!
