       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=]
                                      [--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 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 events executed in parallel.

       --exec-delay=
           Delay the execution of RUN instruction 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.

       --version
           Print version number.

       --help
           Print help text.

ENVIRONMENT
       $UDEV_LOG=
           Set the logging priority.

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

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

CONFIGURATION FILE
       udev expects its main configuration file at /etc/udev/udev.conf. It
       consists of a set of variables allowing the user to override default
       udev values. All empty lines or lines beginning with '#' are ignored.
       The following variables can be set:

       udev_log
           The logging priority. Valid values are the numerical syslog
           priorities or their textual representations: err, info and debug.
