Right, so my only concern is running mtree 
during the build to create staging tree.

Most makefiles rely on the dir they are going to install into existing,
and install cannot tell from its arguments whether the destination
should be a file or a directory.

So I'm curios as to why the filtering that made it safe to use mtree was
removed and what if anything replaced it.
