MAAS leaves behind an empty database config, region controller fails to start
Purge databases and configs from previous install attempt
root@spoink:/etc# apt-get purge maas maas-dns maas-dhcp maas-proxy maas-region-controller-min postgresql postgresql-common bind9

Remove dnssec-validation duplicate config
root@spoink:~# vi /etc/bind/named.conf.options

* Stopping domain name service... bind9
rndc: connect failed: 127.0.0.1#953: connection refused
...done.

...done.
Check database config:
root@spoink:~# cat /etc/maas/regiond.conf
database_host: localhost
database_name: ''
database_pass: ''
database_user: ''
...
Reconfig, just to make sure -- the region controller seems to start fine:
root@spoink:~# dpkg-reconfigure -fnoninteractive maas-region-controller
* Stopping web server apache2
*
maas-regiond stop/waiting
maas-regiond start/running

...done.
maas-clusterd stop/waiting
maas-clusterd start/running, process 17899
But it's not actually functional:
root@spoink:~# maas-region-admin createadmin --username=maas-root --password=sikkrit --email=root+bootstack-$(hostname)@canonical.com

HI Peter,
I've tried to reproduce this over and over, but I've been unable to reproduce it. I have two questions:
1. When you purged MAAS, did you answer Yes to all questions asked about purging the DB?
2. Can you reproduce this consistently?
Marking this incomplete as I can't seem to reproduce it in various environments.
