[001] Installation
________________________________________________________________________________

+------------------------------------------------------------------------------+
|                                                                              |
|  $ kiss b libudev-zero                                                       |
|                                                                              |
+------------------------------------------------------------------------------+


[002] Setup
________________________________________________________________________________

If using mdev or mdevd (with the default configuration files), libudev-zero will
automatically be used once installed. If not, the following configuration must
be done for hotplugging to work.


--[003] Configure mdev For Hotplugging -----------------------------------------

  Add the folllowing to your /etc/mdev.conf.

  +----------------------------------------------------------------------------+
  |                                                                            |
  |  SUBSYSTEM=drm;.*   root:video 660 *libudev-zero-helper                    |
  |  SUBSYSTEM=input;.* root:input 660 *libudev-zero-helper                    |
  |                                                                            |
  +----------------------------------------------------------------------------+


--[004] Configure mdevd For Hotplugging ----------------------------------------

  Ensure that mdevd is started with the flags '-O 4'. This will make the daemon
  rebroadcast kernel uevents to libudev-zero. The distribution's default service
  runs mdevd with these flags.
