udevcontrol

NAME

udevd - event managing daemon

SYNOPSIS

udevd [--daemon] [--debug-trace] [--verbose] [--version] [--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.

--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.

ENVIRONMENT

UDEV_LOG

Overrides the syslog priority specified in the config file.
