udevcontrol8
Event managing daemon
Part of udevd(8).
Usage
udevd [--daemon]
[--debug-trace]
[--verbose]
[--help]
udevcontrol command
Overview
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.
