All rule files are sorted and processed in lexical order, regardless
in which of these directories they live. Files in
<filename>/etc/udev/rules.d/</filename> have precedence over files with
device. This can only be used for very short running tasks. Running an
event process for a long period of time may block all further events for
this or a dependent device. Long running tasks need to be immediately
- detached from the event process itself. If the option
- <option>RUN{<replaceable>fail_event_on_error</replaceable>}</option> is
- specified, and the executed program returns non-zero, the event will be
- marked as failed for a possible later handling.</para>

<para>If no absolute path is given, the program is expected to live in
<filename>/lib/udev</filename>, otherwise the absolute path must be
specified. Program name and arguments are separated by spaces. Single quotes
