Thanks Ross!
That was very helpful.
kill didn't have any effect, but the systemctl command brought the VPS
down, so I guess systemd had got into a bad state.
I wasn't worried about an fsck, but if there was one it was so fast I
didn't notice (which is possible I guess, small disk on SSD) but either
way the VPS is back up and running now and I've learnt something today.
Thanks again :)
Andy
