 .SH "DESCRIPTION"
-.B udevd
-allows the serialization of
-.BR hotplug (8)
-events. The events generated by the kernel may arrive in random order
-in userspace, that makes it neccessary to reorder them.
-.br
-.B udevd
-takes care of the kernel supplied
-.B SEQNUM
-sequence number and arranges the events for execution in the correct order.
-Missing sequences delay the execution of the following events until a timeout
-is reached. Events without any sequence number are bypassing the queue and
-will be executed immediately.
-.br
-For each event a
-.BR udev (8)
-instance is executed in the background with the complete environment received
-by the hotplug event. All further events for the same device are delayed until
-the execution is finished. This way there will never be more than one instance
-running for a single device at the same time.
-.br
-.B udevd
-receives the events from
-.B udevsend
-If
-.B udevd
-isn't already running,
-.B udevsend
-will start it.
+.PP
+udevd listens to kernel uevents and passes the incoming events to udev. It ensures the right event order and takes care, that events for child devices are delayed until the parent has finished the device handling.
+.SH "OPTIONS"
+.TP
+\fB\-\-daemon\fR
+Detach and run in the background.
+.TP
+\fBlog_priority=\fR\fB\fIvalue\fR\fR
+udevcontrol can dynamically set the log level of udevd. Valid values are the numerical syslog priorities or their textual representations: 
+\fBerr\fR, 
+\fBinfo\fR 
+and 
+\fBdebug\fR.
+.TP
+\fBstop_exec_queue\fR
+udevcontrol stops the execution of events from udevd.
+.TP
+\fBstart_exec_queue\fR
+udevcontrol starts the execution of events from udevd.
+.SH "ENVIRONMENT"
+.TP
+\fBUDEV_LOG\fR
+Overrides the syslog priority specified in the config file.
