August 2005 udev udevd 8 udevdevent managing daemon udevd --daemon --debug-trace --verbose --version --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 continuous operation is needed, where no events are processed in parallel. --verbose Print log messages to stdout. --version Print version number. --help Print usage. log_priority=value Set the internal log level of udevd. Valid values are the numerical syslog priorities or their textual representations: err, info and debug. stop_exec_queue Signal udevd to stop executing new events. Incoming events will be queued. start_exec_queue Signal udevd to enable the execution of events. reload_rules Signal udevd to reload the rules from the config. env var=value Set global variable. max_childs Set the maximum number of events, udevd will handle at the same time. max_childs_running Set the maximum number of events, which are allowed to run at the same time. help Print help text. UDEV_LOG Overrides the syslog priority specified in the config file. Written by Kay Sievers kay.sievers@vrfy.org. udev8 , udevadm8
