-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
-currently *not* available.
-Nevertheless it's now possible to add proper udev rules so that the
-DVB device nodes are created automatically.
-We assume that you have udev already up and running and that have been
-creating the DVB device nodes manually up to now due to the missing sysfs
-0. Don't forget to disable your current method of creating the
-device nodes manually.
-1. Unfortunately, you'll need a helper script to transform the kernel
-sysfs device name into the well known dvb adapter / device naming scheme.
-The script should be called "" and should be placed into a script
-dir where udev can execute it, most likely /etc/udev/scripts/
-So, create a new file /etc/udev/scripts/ and add the following:
-/bin/echo $1 | /bin/sed -e 's,dvb\([0-9]\)\.\([^0-9]*\)\([0-9]\),dvb/adapter\1/\2\3,'
-Don't forget to make the script executable with "chmod".
-1. You need to create a proper udev rule that will create the device nodes
-like you know them. All real distributions out there scan the /etc/udev/rules.d
-directory for rule files. The main udev configuration file /etc/udev/udev.conf
-will tell you the directory where the rules are, most likely it's /etc/udev/rules.d/
-Create a new rule file in that directory called "dvb.rule" and add the following line:
-KERNEL="dvb*", PROGRAM="/etc/udev/scripts/ %k", NAME="%c"
-If you want more control over the device nodes (for example a special group membership)
-have a look at "man udev".
-For every device that registers to the sysfs subsystem with a "dvb" prefix,
-the helper script /etc/udev/scripts/ is invoked, which will then
-create the proper device node in your /dev/ directory.
