Patches that don't follow the conceptional design of complex data structures
easily break functions that the author of the patch is not aware of.

I tought that I did already mention it.

SuSE implements a "device manager" deamon that opens device nodes for other
programs. This daemon is less secure than cdrecord/libscg as libscg 
does far more than a simple string compare/pattern matching on the device node
name.

Linux does not implement a device node system with a stable device <-> node 
relation. Libscg maps device node names to more stable bus/target/lun
values and is thus more secure than the simple system used by SuSE.
