I was also intending to look at this.  Sorry I haven't yet.

In addition, I'd like to add one more option to support optional
arguments to the unionfs command.  Specifically because we've run into
some performance issues here in our environment (we use NIS, ick) where
the unionfs mounts are bind mounted elsewhere on the system and then
exported via NFS.  uid/gid ownership is pretty slow.  Having nscd on
helps quite a bit, but I'm wondering if some of the more obscure
unionfs parameters would help more -- in which case an option to
override them in the config file would be useful.
