UDEV.CONF(5) udev.conf UDEV.CONF(5)
udev.conf - Configuration for device event managing daemon
/etc/udev/udev.conf
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 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.
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=
Specifes 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)).
