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.
The following options can be set:
udev_log=
¶The log level. Valid values are the numerical
syslog priorities or their textual representations:
err
, info
and
debug
.
This option is also honored by udevadm(8).
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.
exec_delay=
¶An integer. Delay the execution of each RUN{
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.program
}
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)).
