-This mode is used when run via the \fBudev\fP PROGRAM key. Passing any
-arguments or options as part of the PROGRAM rule breaks this assumption,
-and the results will likely not be as expected.
-
-When in this mode, all errors and warnings are sent via syslog.
-
-To determine the specific value needed in a RESULT key, use the \-s option,
-for example:
-
-.sp
-.nf
-/sbin/scsi_id -s /block/sda
-.fi
-.P
-
-An example \fBudev\fP rule using \fBscsi_id\fP, that will name a block
-device and any partitions for the device matching the \fBscsi_id\fP output
-of 312345:
-
-.sp
-.nf
-BUS="scsi", PROGRAM="/sbin/scsi_id", RESULT="312345", NAME="disk%n"
-.fi
+If the DEVPATH environment variable is set, scsi_id assumes it has been
+invoked via udev (or some other hotplug program), and all errors or
+warnings are sent using syslog.
