- DESCRIPTION
- udevd listens to kernel uevents and passes the incoming events to
- udev. It ensures the correct event order and takes care, that events for child
- devices are delayed until the parent event has finished the device handling.
- The behavior of the running daemon can be changed with
- udevadm control.
-
+ Description
+ udevd listens to kernel uevents. For every event, udevd executes matching
+ instructions specified in udev rules. See
+ udev7
+ .
+ On startup the content of the directory /lib/udev/devices
+ is copied to /dev. If kernel modules specify static device
+ nodes, these nodes are created even without a corresponding kernel device, to
+ allow on-demand loading of kernel modules. Matching permissions specified in udev
+ rules are applied to these static device nodes.
+ The behavior of the running daemon can be changed with
+ udevadm control.
+
- OPTIONS
-
-
-
-
- Detach and run in the background.
-
-
-
-
-
- Run all events completely serialized. This may be useful if udev triggers
- actions or loads kernel modules which cause problems and a slow but continuous
- operation is needed, where no events are processed in parallel.
-
-
-
-
-
-
- Print debug messages to stderr.
-
-
-
-
-
- Specify when udevd should resolve names of users and groups.
- When set to (the default) names will be
- resolved when the rules are parsed. When set to
- names will be resolved for every event.
- When set to names will never be resolved
- and all devices will be owned by root.
-
-
-
-
-
- Print version number.
