An empty package by definition doesn't have any impact on the rootfs, 
because it's empty.  The majority of empty packages are used for their 
dependency management: package groups are just empty packages which have 
dependencies.

If you know of any empty packages which have no dependencies, feel free 
to submit a patch to remove them from the metadata.
