Ok, thanks. Sounds reasonable to add, as long as we document that the
correct way to do it is /opt, but we are providing /cross as a
backwards-compatible method while people migrate over.

If you address my code review comments, and I get a consensus from
Clark, these patches can go in.

There was a comment last night on IRC that the patches dont apply
cleanly and that maybe you missed sending a patch set or something.
Please base off latest git tree, master branch when resending. You used
git-format-patch to send it, which is good. Please continue to do that.
