+# 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.
