NAME
       systemd-udevd.service, systemd-udevd-control.socket, systemd-udevd-kernel.socket, systemd-
       udevd - Device event managing daemon

SYNOPSIS
       systemd-udevd.service

       systemd-udevd-control.socket

       systemd-udevd-kernel.socket

       /usr/lib/systemd/systemd-udevd [--daemon] [--debug] [--children-max=] [--exec-delay=]
                                      [--event-timeout=] [--resolve-names=early|late|never]
                                      [--version] [--help]

DESCRIPTION
       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 daemon can be configured using udev.conf(5), its command line options,
       environment variables, and on the kernel command line, or changed dynamically with udevadm
       control.

OPTIONS
       --daemon
           Detach and run in the background.

       --debug
           Print debug messages to standard error.

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

       --exec-delay=
           Delay the execution of RUN instructions by the given number of seconds. This option
           might be useful when debugging system crashes during coldplug caused by loading
           non-working kernel modules.

       --event-timeout=
           Set the number of seconds to wait for events to finish. After this time the event will
           be terminated. The default is 30 seconds.

       --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.

       --help
           Print a short help text and exit.

       --version
           Print a short version string and exit.

KERNEL COMMAND LINE
       Parameters starting with "rd." will be read when systemd-udevd is used in an initrd.

       udev.log-priority=, rd.udev.log-priority=
           Set the log level.

       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 instructions by the given number of seconds. This option
           might be useful when debugging system crashes during coldplug caused by loading
           non-working kernel modules.

       udev.event-timeout=, rd.udev.event-timeout=
           Wait for events to finish up to the given number of seconds. This option might be
           useful if events are terminated due to kernel drivers taking too long to initialize.

       net.ifnames=
           Network interfaces are renamed to give them predictable names when possible. It is
           enabled by default; specifying 0 disables it.
