Comment 1 for bug 1717477

I can reproduce this fairly easily with a standard ubuntu image.

a.) launch an instance on openstack (or somewhere with an additional disk)

   upgrade cloud-init if necessary.

b.) create a filesystem and put it in /etc/fstab with simple options.
  on my opensstack cloud-init sets up an entry like:

   /dev/vdb /mnt auto defaults,nofail,x-systemd.requires=cloud-init.service,comment=cloudconfig 0 2

  but what we want is just a simple line:

   /dev/vdb /mnt auto defaults 0 2

c.) reboot

I'm attaching 'journal -o short-precise' output for first boot and after reboot (with the failure).
