Greetings,
I know this may sound odd, but I would start by setting the grub
environment to boot this instance into single user mode if you can.
Be aware that "systemd" is new and quite controversial, and in many ways
is likely buggy. So the approach I would take once I was on the system as
single user or with the quiesced boot drive NFS mounted to another system
(This might be problematic in itself :^), I would figure out how to stop
"udevd" from starting up. I would try looking for "udevd" depending on
the tools at hand and available. Good possibilities include:
/sbin/udevd
/lib/systemd/systemd-udevd
That said, your mileage may vary.
Good luck and...
Kindest Regards,
Paul Flint

So the log is filling with:

It seems like systemd is writing a heap of messages an wrapping. It'd be
nice to see what gumpf is being logged. However, when the boot eventually fails
we never drop into a shell and just get thousands of these messages:
systemd[1]: Failed to accept private connection, ignoring: Function not
implemented
I guess if I can work out what messages are being logged then I'll find the
underlying problem
