MetaSchema get_meta_doc) 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. 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.
