Public bug reported:

When I boot the latest xenial Azure image (containing cloud-init
0.7.8-49-g9e904bb-0ubuntu1~16.04.1), the ephemeral disk does not end up
mounted (though it is formatted appropriately).  Restarting the
mnt.mount service does mount it, which suggests there is an issue in the
ordering of the services at boot.
