Hi Richard,
Could you please have a look at this?

You gave me some suggestions on a similar problem before (mdadm 
udev-rules-dir problem, bug#2804).
As the same problem is encountered in other packages, I have to ask:
Are we going to take the approach of fixing every package that hardcodes 
udev-rules-dir, as suggested by Constantin?

Thanks,
Chen Qi
