kernel.socket, systemd-udevd - Device event managing daemon
/usr/lib/systemd/systemd-udevd [--daemon] [--debug] [--children-max=]
systemd-udevd listens to kernel uevents. For every event, systemd-udevd
executes matching instructions specified in udev rules. See udev(7).
The behavior of the running daemon can be changed with udevadm control.
Detach and run in the background.
Print debug messages to stderr.
Limit the number of events executed in parallel.
Delay the execution of RUN instruction by the given number of
seconds. This option might be useful when debugging system crashes
during coldplug caused by loading non-working kernel modules.
Specify when systemd-udevd should resolve names of users and
groups. When set to early (the default) names will be resolved when
the rules are parsed. When set to late names will be resolved for
every event. When set to never names will never be resolved and all
devices will be owned by root.
Print version number.
Print help text.
Set the logging priority.
