The status-quo right now is that custom hotplug scripts cannot be used
in conjunction with pygrub, because we need to pass pygrub either a
block device or a raw file. This patch adds the necessary functionality
in order to attach the block device before executing pygrub, so we can
use this new hotplug scripts with pygrub, providing extra functionality.
