# Some files to look around:
#
#   /sys/class/dmi/id/board_serial
#   /sys/class/dmi/id/product_uuid
#   /var/lib/dbus/machine-id
#
# This would work in some systems, while in others wont:
#
#   manufacturer="`$SUDO dmidecode -s system-manufacturer`"
#   version="`$SUDO dmidecode -s system-version`"
#
# Best way would either get a UUID from BIOS or build our own, manual database with arbitrary generated UUIDs.
