+ 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
+ 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 /usr/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.
