-.SH USAGE WITH UDEV
-If \fBscsi_id\fP is invoked with one argument without a leading \-, it
-assumes it is called for a hotplug event, and looks for the sysfs device
-in the DEVPATH environment variable.
-
-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
-.P
