Ok, I'm bringing up this old topic, because as was correctly stated, SKDs use 
-dev packages and if we don't fix the symlink pointing to /lib/libvolume.so.0, 
it breaks those SDKs. There is also another side-effect - libvolume-id-dev.ipk 
misses the automatic dependency on libvolume-id0.ipk so the SDK cannot just 
refer to the -dev package and expect the actual library to be installed. In 
that case only the broken link gets installed...

So, if nobody objects, I'm going to apply my first patch from this thread 
against the udev recipe, fixing .so symlink to be relative.
