NAME
       udevd - event managing daemon

SYNOPSIS
       udevd [--daemon] [--debug-trace] [--verbose] [--help]

       udevcontrol command

DESCRIPTION
       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.

OPTIONS
       --daemon
	   Detach and run in the background.

       --debug-trace
	   Run all events completely serialized. This may be useful if udev
	   triggers actions or loads kernel modules which cause problems and a
	   slow but continuous operation is needed, where no events are
	   processed in parallel.

       --verbose
	   Print log messages to stdout.

       --help
	   Print usage.

       log_priority=value
	   udevcontrol can dynamically set the log level of udevd. Valid
	   values are the numerical syslog priorities or their textual
	   representations: err, info and debug.

       stop_exec_queue
	   udevcontrol stops the execution of events from udevd.

       start_exec_queue
	   udevcontrol starts the execution of events from udevd.

ENVIRONMENT
       UDEV_LOG
	   Overrides the syslog priority specified in the config file.
