I have no objection at all to libudev. After all, stripped it is less 
than 40k (no to mention that it only adds 16k to the squashfs image) and 
it does not come with additional configurations and daemons that are not 
already required for udev operation. At the moment is it not included 
because nothing depends on it, which I suspect is due to the fact that 
it is relatively new.
