Both of these are likely to be harder than just changing the image to
add the appropriate bit of configuration, IMO.  cloud-init makes sense
when you're using unmodified cloud images, but we already have a
pipeline for modifying images for our use;
is the key bit here.  (But I'd still need to know what exactly we need
to set there.)

I'd still like it to be fixed in bionic's systemd, even if we need to
work around it in the short term.
