-.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 deprecated, but
-available for backwards compatibility.
-
-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.
-
-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 -d %N -s %p", RESULT="312345", NAME="disk%n"
-.fi
-.P
