12 systemd-udevd(8) expects its main configuration file at
13 /etc/udev/udev.conf. It consists of a set of variables allowing the
14 user to override default udev values. All empty lines or lines
15 beginning with '#' are ignored. The following variables can be set:
16
17 udev_log=
18 The log level. Valid values are the numerical syslog priorities or
19 their textual representations: err, info and debug.
20
21 children_max=
22 An integer. The maximum number of events executed in parallel.
23
24 This is the same as the --children-max= option.
25
26 exec_delay=
27 An integer. Delay the execution of RUN instructions by the given
28 number of seconds. This option might be useful when debugging
29 system crashes during coldplug caused by loading non-working kernel
30 modules.
31
32 This is the same as the --exec-delay= option.
33
34 event_timeout=
35 An integer. The number of seconds to wait for events to finish.
36 After this time, the event will be terminated. The default is 180
37 seconds.
38
39 This is the same as the --event-timeout= option.
40
41 resolve_names=
42 Specifes when systemd-udevd should resolve names of users and
43 groups. When set to early (the default), names will be resolved
44 when the rules are parsed. When set to late, names will be resolved
45 for every event. When set to never, names will never be resolved
46 and all devices will be owned by root.
47
48 This is the same as the --resolve-names= option.
49
50 In addition, systemd-udevd can be configured by command line options
51 and the kernel command line (see systemd-udevd(8)).
