PATCH:failed to unlink /var/lib/rpm/__db.xxx



hi, anaconda developpers

I always found the following message in anaconda.log after
FC6 updgrade installation.
-------------
failed to unlink /var/lib/rpm/__db.000
-------------
and I checked anaconda source and it's no problem,
but It looks not good.
How about checking __db.xxx exists or not before unlink?
