+.SH "NAME"
+udev.conf \- Configuration for device event managing daemon
+.SH "SYNOPSIS"
+.PP
+/etc/udev/udev\&.conf
+.SH "DESCRIPTION"
+.PP
+\fBsystemd-udevd\fR(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 \*(Aq#\*(Aq are ignored\&. The following variables can be set:
+.PP
+\fIudev_log=\fR
+.RS 4
+The log level\&. Valid values are the numerical syslog priorities or their textual representations:
+\fBerr\fR,
+\fBinfo\fR
+and
+\fBdebug\fR\&.
+.sp
+Added in version 216\&.
+.RE
+.PP
+\fIchildren_max=\fR
+.RS 4
+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\&.
+.sp
+This is the same as the
+\fB\-\-children\-max=\fR
+option\&.
+.sp
+Added in version 240\&.
+.RE
+.PP
+\fIexec_delay=\fR
+.RS 4
+An integer\&. Delay the execution of each
+\fIRUN{\fR\fI\fIprogram\fR\fR\fI}\fR
+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\&.
+.sp
+This is the same as the
+\fB\-\-exec\-delay=\fR
+option\&.
+.sp
+Added in version 240\&.
+.RE
+.PP
+\fIevent_timeout=\fR
+.RS 4
+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\&.
+.sp
+This is the same as the
+\fB\-\-event\-timeout=\fR
+option\&.
+.sp
+Added in version 240\&.
+.RE
+.PP
+\fIresolve_names=\fR
+.RS 4
+Specifies when systemd\-udevd should resolve names of users and groups\&. When set to
+\fBearly\fR
+(the default), names will be resolved when the rules are parsed\&. When set to
+\fBlate\fR, names will be resolved for every event\&. When set to
+\fBnever\fR, names will never be resolved and all devices will be owned by root\&.
+.sp
+This is the same as the
+\fB\-\-resolve\-names=\fR
+option\&.
+.sp
+Added in version 240\&.
+.RE
+.PP
+\fItimeout_signal=\fR
+.RS 4
+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
+\fBSIGKILL\fR\&.
+.sp
+Added in version 246\&.
+.RE
+.PP
+In addition,
+systemd\-udevd
+can be configured by command line options and the kernel command line (see
+\fBsystemd-udevd\fR(8))\&.
