UDEV.CONF(5) udev.conf 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=
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)).
