If these configs are provided as a dictionary, the keys are only used to order the execution of the assertions or commands and the dictionary is merged with any vendor-data snap configuration provided. If a list is provided by the user instead of a dict, any vendor-data snap configuration is ignored. The ``assertions`` configuration option is a dictionary or list of properly-signed snap assertions which will run before any snap ``commands``. They will be added to snapd's assertion database by invoking ``snap ack <aggregate_assertion_file>``. Snap ``commands`` is a dictionary or list of individual snap commands to run on the target system. These commands can be used to create snap users, install snaps and provide snap configuration. .. note:: If 'side-loading' private/unpublished snaps on an instance, it is best to create a snap seed directory and seed.yaml manifest in **/var/lib/snapd/seed/** which snapd automatically installs on startup. ax snap: assertions: 00: | signed_assertion_blob_here 02: | signed_assertion_blob_here commands: 00: snap create-user --sudoer --known <snap-user>@mydomain.com 01: snap install canonical-livepatch 02: canonical-livepatch enable <AUTH_TOKEN> ay # Convenience: the snap command can be omitted when specifying commands # as a list and 'snap' will automatically be prepended. # The following commands are equivalent: snap: commands: 00: ['install', 'vlc'] 01: ['snap', 'install', 'vlc'] 02: snap install vlc 03: 'snap install vlc' z� # You can use a list of commands snap: commands: - ['install', 'vlc'] - ['snap', 'install', 'vlc'] - snap install vlc - 'snap install vlc' z� # You can use a list of assertions snap: assertions: - signed_assertion_blob_here - | signed_assertion_blob_here �snap)�id�name�title� description�distros�examples� frequency�activate_by_schema_keys�metac C s� | sdS t �d� t| t�r| �� } n t| t�s tdj| d���td|g}d� | �}| D ]}t �d|� d�dd � � q,t � ||� d �� tj|d d � dS ) a Import list of assertions.
