# This file contains rules for setting udev environment variables based on
# hardware properties (serial numbers etc), which can be obtained without
# actually reading from the device.
#
# Hopefully this will be integrated into systemd/udev soon (as 54-storage-hardware.rules).
# Until then, we ship it here in sg3-utils.
# It's important that rules dealing with low-level hardware attributes run
# before the generic SCSI rules in 55-scsi-sg3_utils.rules.
