/usr/lib/systemd/systemd-udevd [--daemon] [--debug] [--children-max=] [--exec-delay=] [--resolve-names=early|late|never] [--version] [--help]
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.
--daemonDetach and run in the background.
--debugPrint debug messages to stderr.
--children-max=Limit the number of events executed in parallel.
--exec-delay=Delay the execution of RUN intruction by the given number of seconds. This option might be useful when debugging system crashes during coldplug caused by loading non-working kernel modules.
--resolve-names=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.
--versionPrint version number.
--helpPrint help text.
Parameters starting with "rd." will be read when systemd-udevd is used in an initrd.
udev.log-priority=, rd.udev.log-priority=Set the logging priority.
udev.children-max=, rd.udev.children-max=Limit the number of events executed in parallel.
udev.exec-delay=, rd.udev.exec-delay=Delay the execution of RUN intruction by the given number of seconds. This option might be useful when debugging system crashes during coldplug caused by loading non-working kernel modules.
