+UDEV rules for DVB
+==================

+ #) **TODO:** change this document to explain how to make DVB devices
+ persistent, as, when a machine has multiple devices, they may be detected

The DVB subsystem currently registers to the sysfs subsystem using the
"class_simple" interface.
This means that only the basic information like module loading parameters
are presented through sysfs. Other things that might be interesting are

Nevertheless it's now possible to add proper udev rules so that the
DVB device nodes are created automatically.

If you want more control over the device nodes (for example a special group membership)
have a look at "man udev".
