August 2005 udev udevd 8 udevdevent managing daemon udevd --daemon --debug-trace --verbose --help udevcontrol command 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. --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 continiuous 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. UDEV_LOG Overrides the syslog priority specified in the config file. Written by Kay Sievers kay.sievers@vrfy.org. udev7
