features:
- The nova SSH public key distribution has been made a lot faster
especially when deploying against very large clusters. To support
larger clusters the role has moved away from the "authorized_key"
module and is now generating a script to insert keys that may
be missing from the authorized keys file. The script is saved on all
nova compute nodes and can be found at
``/usr/local/bin/openstack-nova-key.sh``. If ever there is a need to
reinsert keys or fix issues on a given compute node the script can be
executed at any time without directly running the ansible playbooks
or roles.
