.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\&.
.RE
.PP
\fIchildren_max=\fR
.RS 4
An integer\&. The maximum number of events executed in parallel\&.
.sp
This is the same as the
\fB\-\-children\-max=\fR
option\&.
.RE
.PP
\fIexec_delay=\fR
.RS 4
An integer\&. Delay the execution of
\fIRUN\fR
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\&.
.sp
This is the same as the
\fB\-\-exec\-delay=\fR
option\&.
.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\&.
.RE
.PP
\fIresolve_names=\fR
.RS 4
Specifes 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\&.
.RE
.PP
In addition,
systemd\-udevd
can be configured by command line options and the kernel command line (see
\fBsystemd-udevd\fR(8))\&.
