.SH "NAME" udev.conf, udev.conf.d - Configuration for device event
managing daemon
.SH "SYNOPSIS"
.PP
.SH "DESCRIPTION"
.PP These files contain configuration options for systemd-udevd(8).
The syntax of these files is very simple: a list of assignments, one per
line. All empty lines or lines beginning with # are ignored.
.PP The following options can be set:
.PP udev_log=
The log level. Valid values are the numerical syslog priorities or their
textual representations: err, info and debug.
.if n .sp
Added in version 216.
.RE
.PP children_max=
An integer. The maximum number of events executed in parallel. When
unspecified or 0 is specified, the maximum is determined based on the system
resources.
This is the same as the --children-max= option.
Added in version 240.
.RE
.PP 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.
Added in version 240.
.RE
.PP 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.
Added in version 240.
.RE
.PP 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.
Added in version 240.
.RE
.PP 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.
Added in version 246.
.RE
.PP In addition, systemd-udevd can be configured by command line options and
the kernel command line (see systemd-udevd(8)).
