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=
           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)).
