- <para>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.

+ <para>udevd listens to kernel uevents and executes the instructions specified
+ in rules. On startup the content of the directory
+ <filename>/lib/udev/devices</filename> is copied to <filename>/dev</filename>.
+ If kernel modules specify static device nodes, these nodes are created
+ even wihtout 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
