# This dictionary is used to map boot device names between two (2) name
# spaces. The name spaces are:
#
#     1) ironic boot devices
#     2) iDRAC boot sources
#
# Mapping can be performed in both directions.
#
# The keys are ironic boot device types. Each value is a list of strings
# that appear in the identifiers of iDRAC boot sources.
#
# The iDRAC represents boot sources with class DCIM_BootSourceSetting
# [1]. Each instance of that class contains a unique identifier, which
# is called an instance identifier, InstanceID,
#
# An InstanceID contains the Fully Qualified Device Descriptor (FQDD) of
# the physical device that hosts the boot source [2].
