NAME

6       udevd - event managing daemon
7

SYNOPSIS

9       udevd [--daemon] [--debug] [--children-max=] [--exec-delay=]
10             [--resolve-names=early|late|never] [--version] [--help]
11

DESCRIPTION

13       udevd listens to kernel uevents. For every event, udevd executes
14       matching instructions specified in udev rules. See udev(7).
15
16       On startup the content of the directory /lib/udev/devices is copied to
17       /dev. If kernel modules specify static device nodes, these nodes are
18       created even wihtout a corresponding kernel device, to allow on-demand
19       loading of kernel modules. Matching permissions specified in udev rules
20       are applied to these static device nodes.
21
22       The behavior of the running daemon can be changed with udevadm control.

OPTIONS

25       --daemon
26           Detach and run in the background.
27
28       --debug
29           Print debug messages to stderr.
30
31       --children-max=
32           Limit the number of parallel executed events.
33
34       --exec-delay=
35           Number of seconds to delay the execution of RUN instructions. This
36           might be useful when debugging system crashes during coldplug cause
37           by loading non-working kernel modules.
38
39       --resolve-names=
40           Specify when udevd should resolve names of users and groups. When
41           set to early (the default) names will be resolved when the rules
42           are parsed. When set to late names will be resolved for every
43           event. When set to never names will never be resolved and all
44           devices will be owned by root.
45
46       --version
47           Print version number.
48
49       --help
50           Print help text.
51

ENVIRONMENT

53       UDEV_LOG=
54           Set the logging priority.
55

KERNEL COMMAND LINE

57       udev.log-priority=
58           Set the logging priority.
59
60       udev.children-max=
61           Limit the number of parallel executed events.
62
63       udev.exec-delay=
64           Number of seconds to delay the execution of RUN instructions. This
65           might be useful when debugging system crashes during coldplug cause
66           by loading non-working kernel modules.
