        When a dataset is rolled back, all data that has changed since
        the snapshot is discarded, and the dataset reverts to the state
        at the time of the snapshot. By default, the command refuses to
        roll back to a snapshot other than the most recent one.

        In order to do so, all intermediate snapshots and bookmarks
        must be destroyed by specifying the -r option.

    Promotes a clone file system to no longer be dependent on its "origin"
    snapshot.

    .. note::

        This makes it possible to destroy the file system that the
        clone was created from. The clone parent-child dependency relationship
        is reversed, so that the origin file system becomes a clone of the
        specified file system.

        The snapshot that was cloned, and any snapshots previous to this
        snapshot, are now owned by the promoted clone. The space they use moves
        from the origin file system to the promoted clone, so enough space must
        be available to accommodate these snapshots. No new space is consumed
        by this operation, but the space accounting is adjusted. The promoted
        clone must not have any conflicting snapshot names of its own. The
        rename subcommand can be used to rename any conflicting snapshots.

    Displays properties for the given datasets.

    dataset : string
        name of snapshot(s), filesystem(s), or volume(s)
    properties : string
        comma-separated list of properties to list, defaults to all
    recursive : boolean
        recursively list children
    depth : int
        recursively list children to depth
    fields : string
        comma-separated list of fields to include, the name and property field will always be added
    type : string
        comma-separated list of types to display, where type is one of
        filesystem, snapshot, volume, bookmark, or all.

        .. versionchanged:: 3004

        type is ignored on Solaris 10 and 11 since not a valid parameter on those platforms

    source : string
        comma-separated list of sources to display. Must be one of the following:
        local, default, inherited, temporary, and none. The default value is all sources.
    parsable : boolean
        display numbers in parsable (exact) values (default = True)

        If no datasets are specified, then the command displays properties
        for all datasets on the system.
