UDEV.CONF(5)                                         UDEV.CONF(5)

     NAME
          udev.conf - Configuration for device event managing daemon

     SYNOPSIS
          /etc/udev/udev.conf

     DESCRIPTION
          systemd-udevd(8) 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 log level. Valid values are the numerical syslog
              priorities or their textual representations: err, info
              and debug.

          children_max=
              An integer. The maximum number of events executed in
              parallel.

              This is the same as the --children-max= option.

          exec_delay=
              An integer. Delay the execution of each RUN{program}
              parameter by the given number of seconds. This option
              might be useful when debugging system crashes during
              coldplug caused by loading non-working kernel modules.

              This is the same as the --exec-delay= option.

          event_timeout=
              An integer. The number of seconds to wait for events to
              finish. After this time, the event will be terminated.
              The default is 180 seconds.

              This is the same as the --event-timeout= option.

          resolve_names=
              Specifies 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.

              This is the same as the --resolve-names= option.

          timeout_signal=

     UDEV.CONF(5)                                         UDEV.CONF(5)

              Specifies a signal that systemd-udevd will send on
              worker timeouts. Note that both workers and spawned
              processes will be killed using this signal. Defaults to
              SIGKILL.

          In addition, systemd-udevd can be configured by command line
          options and the kernel command line (see systemd-udevd(8)).
