�PER_INSTANCE)
�ProcessExecutionErrora�Configure which device is used as the target for grub installation. This module
can be enabled/disabled using the ``enabled`` config key in the ``grub_dpkg``
config dict. The global config key ``grub-dpkg`` is an alias for ``grub_dpkg``.
If no installation device is specified this module will execute grub-probe to
determine which disk the /boot directory is associated with.

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.
