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.
--daemon
Detach and run in the background.
--debug
Print debug messages to stderr.
--children-max=
Limit the number of parallel executed events.
--exec-delay=
Number of seconds to delay the execution of RUN instructions. This might be useful when debugging system crashes during coldplug cause 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.
--version
Print version number.
--help
Print help text.
The parameters starting with "rd.", will be read when udev 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 parallel executed events.
udev.exec-delay=
, rd.udev.exec-delay=
Number of seconds to delay the execution of RUN instructions. This might be useful when debugging system crashes during coldplug cause by loading non-working kernel modules.
