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 ``. 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 note:: If 'side-loading' private/unpublished snaps on an instance, it is best to create a snap seed directory and seed.yaml manifest in **/var/lib/snapd/seed/** which snapd automatically installs on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. **Development only**: The ``squashfuse_in_container`` boolean can be set true to install squashfuse package when in a container to enable snap installs. Default is false. t descriptiontdistrosst snap: assertions: 00: | signed_assertion_blob_here 02: | signed_assertion_blob_here commands: 00: snap create-user --sudoer --known @mydomain.com 01: snap install canonical-livepatch 02: canonical-livepatch enable sÑ # LXC-based containers require squashfuse before snaps can be installed snap: commands: 00: apt-get install squashfuse -y 11: snap install emoj s‹ # 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' texamplest frequencytobjectttypetarraytstringtitemstadditionalItemsitminItemst minPropertiest uniqueItemst assertionstoneOftcommandstbooleantsquashfuse_in_containert propertiestadditionalPropertiestrequiredtsnaps(/var/lib/cloud/instance/snapd.assertionscCsâ|s dStjdƒt|tƒr5|jƒ}n*t|tƒs_tdjd|ƒƒ‚ntdg}dj |ƒ}x.|D]&}tjd|j dƒdd !ƒqWt j t |jd ƒƒt j|t gd tƒdS( sImport list of assertions.
