NAME
udevd - event managing daemon
SYNOPSIS
udevd [--daemon] [--debug-trace] [--debug] [--version] [--help]
DESCRIPTION
udevd listens to kernel uevents and passes the incoming events to udev.
It ensures the correct event order and takes care, that events for
child devices are delayed until the parent event has finished the
device handling. The behavior of the running daemon can be changed with
udevadm control.
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.
--debug
Print log messages to stdout.
--version
Print version number.
help
Print help text.
ENVIRONMENT
UDEV_LOG
Overrides the syslog priority specified in the config file.
