regression: nova boot --file does not work

[Martin Pitt]

Since more often than not cloud instances have a broken /etc/hosts, autopkgtest's nova setup script does this to force an update of /etc/hosts to include the own hostname:

    # cloud-init config to fix broken hostname resolution
    local cfg=`mktemp`
    echo "manage_etc_hosts: true" > $cfg

    nova boot --flavor $FLAVOR --key_name $KEYNAME \
        --file /etc/cloud/cloud.cfg.d/01manage_hosts.cfg=$cfg \
        --image $IMAGE $NET_ID --poll $SRVNAME

This did work in the past (several months ago, thus in the saucy/trusty era, with Canonistack), but seems to have broken in utopic or with Bootstack:

$ cat /tmp/cfg
manage_etc_hosts: true
$ nova boot --flavor m1.small --key_name pitti --image ubuntu-utopic-14.10-beta2-amd64-server-20140923-disk1.img --nic net-id=415a0839-eb05-4e7a-907c-413c657f4bf5 --file /etc/cloud/cloud.cfg.d/01manage_hosts.cfg=/tmp/cfg --poll adt-nova-1
$ ssh -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no ubuntu@172.19.0.90
ubuntu@adt-nova-1:~$ ls /etc/cloud/cloud.cfg.d/
05_logging.cfg 90_dpkg.cfg README

I. e. the file is not there. /var/log/cloud-init.log has no trace of this, but then I'm not sure whether --file is supposed to reflect in cloud-init.log (the effect of installing the file certainly should though, but it's not even getting that far).
