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.
