This module can be enabled/disabled using the ``enabled`` config key in the ``grub_dpkg`` config dict. This module automatically selects a disk using ``grub-probe`` if no installation device is specified. The value which is placed into the debconf database is in the format which the grub postinstall script expects. Normally, this is a /dev/disk/by-id/ value, but we do fallback to the plain disk name if a by-id name is not present. If this module is executed inside a container, then the debconf database is seeded with empty values, and install_devices_empty is set to true. �ubuntu�debian� cc_grub_dpkgz Grub Dpkgz*Configure grub debconf installation deviceaE grub_dpkg: enabled: true # BIOS mode (install_devices needs disk) grub-pc/install_devices: /dev/sda grub-pc/install_devices_empty: false # EFI mode (install_devices needs partition) grub-efi/install_devices: /dev/sda )�id�name�title� description�distros� frequency�examples�activate_by_schema_keys�metac C sb d} g }d}d}t � rd}d}ztjdd||gdd �j�� } W n8 tyI } z t|jt�r3t� d � n d |j v r>t� d � n� W Y d }~nd }~w t yW t � td� Y nw | r`tj�| �sbdS ztjdddd| gdd �j�� �� }W n t y� t � td| � Y nw t� dd�|�� dd� |D �}t� dd�|�� |r�t|�d n| }t� d|� |S )z� Fetches the /dev/disk/by-id device grub is installed to.
