Rackspace, cloud-init and old Trusty Image IDs.

Turns out that if you're using this version of the Ubuntu 14.04 Image and you do an apt-get upgrade then it seems to overwrite /etc/init/cloud-init-local.conf which appears to cause the next boot to fail.

It is the only difference I could find when building the image repeatadly over the last few hours.

Getting the Rackspace Nova client upgraded (my old one didn't work) so that I could see the current Ubuntu Trusty Image ID gave me a different problem with the new image (28153eac-1bae-4039-8d9f-f8b513241efe) that I have now dealt with.

Wish list: It would be very nice if there were easily findable lists of Image IDs kind of like this:

http://cloud-images.ubuntu.com/trusty/current/

Userdata for octohost on Digital Ocean with ZFS - be careful - it might eat your data.
export PUBLIC_IPV4=$(curl -s http://169.254.169.254/metadata/v1/interfaces/public/0/ipv4/address)
export CONSUL_KEY=$(consul keygen)
service consul stop
rm -rf /var/cache/octohost/*
sudo cat > /etc/consul.d/default.json << EOL
