Dell iDRAC facter plugin

drac.rb

# Fact: racadm
#
# Purpose: Return the racadm information from Dell hardware
#
# Resolution:
#   On Linux, queries racadm getconfig -g for each group in the query hash
#
# Author: Mikael Fridh <mfridh@marinsoftware.com>
#
# TODO Instead of sweeping output once per key, sweep once and
#      lookup keys in hash (racadm output format seems more reliable than
#      dmidecode anyway. ( cfgKeyName=value )
