Comment 9 for bug 1766287

To recreate:

- install the google-cloud-sdk and configure your gcloud command line
- cat >user-data.yaml <<EOF
#cloud-config
ssh_import_id: lp:<your lp id>
EOF

# launch instance that can recreate
- gcloud compute instances create recreate-lp1766287 --zone=europe-west1 --image daily-ubuntu-minimal-1804-bionic-v20180420 --metadata-from-file user-data=user-data.yaml --metadata=serial-port-enable=1

# get the ip of the instance into variable
- IP=`gcloud compute instances list | awk '/recreate-lp1766287/ {print $5}'`

# connect to instance
- ssh ubuntu@$IP;

# on the instance, set root password for serial console login
- sudo bash; passwd

# update cloud-init-local.service config to Want/After systemd-udev-settle.service
- sudo sed -i -e '/DefaultDependencies/i Wants=systemd-udev-settle.service\nAfter=systemd-udev-settle.service' /lib/systemd/system/cloud-init-local.service

# reset cloud-init
- sudo cloud-init clean --logs --reboot

# in separate terminal, fire up serial console
- cloud compute connect-to-serial-port recreate-lp1766287

# In the shell with the IP variable defined,
# Run this loop to watch and trigger reboots if network comes up:

- COUNT=0; while true; do echo "---"; echo "COUNT=$COUNT"; ssh -o ConnectTimeout=5s ubuntu@$IP -- "sudo cloud-init status --wait; sudo cloud-init clean --logs; sudo shutdown --reboot +1; exit" 2>/dev/null; if [ "$?" = "0" ]; then echo "Boot Success!"; COUNT=$(($COUNT + 1)); fi; echo "waiting 4s"; sleep 4; done
