Comment 13 for bug 1927020

What happens when you do:

sudo dpkg-reconfigure cloud-init --frontend=noninteractive

do you see /etc/cloud/cloud.cfg.d/ populated?

if not you can modify /var/lib/dpkg/info/cloud-init.postinst shebang to include execution trace:

#!/bin/sh -x

Then re-run the command and capture the output. Maybe we can see why that's not rendering the maas cloud config files.

FWIW, I've extracted the debconf_selections into a file, populated debconf, then re-run dpkg-reconfigure cloud-init and see that it does write out these files in /etc/cloud/cloud.cfg.d/
