Not really. The main problem is knowing which file to be filtered out.
You would need to supply a list of files to exclude, which would
unnecessarily complicate unionmount IMHO.
A cleaner solution would be to first mount a hypothetical ``filterfs''
that removes the files, and then do a unionmount on top of that. Also you
could just simply set a lib.so.1 -> lib.so.3 symlink in the mountee, which
would shadow the underlying lib.so.1.
