UDEVD(8)							       udevd								  UDEVD(8)

NAME

       udevd - event managing daemon

SYNOPSIS

       udevd [--daemon] [--debug] [--children-max=] [--exec-delay=] [--resolve-names=early|late|never] [--version] [--help]

DESCRIPTION

       udevd listens to kernel uevents. For every event, udevd executes matching instructions specified in udev rules. See udev(7).

       On startup the content of the directory /lib/udev/devices is copied to /dev. If kernel modules specify static device nodes, these nodes are
       created even without a corresponding kernel device, to allow on-demand loading of kernel modules. Matching permissions specified in udev
       rules are applied to these static device nodes.

       The behavior of the running daemon can be changed with udevadm control.

OPTIONS

       --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 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.

ENVIRONMENT

       UDEV_LOG=
	   Set the logging priority.

KERNEL COMMAND LINE

       udev.log-priority=
	   Set the logging priority.

       udev.children-max=
	   Limit the number of parallel executed events.

       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.
