As a tangent, because this has never made sense to me: Is there a reason this is all looking to merge /* into /usr/* instead of the other way around? The latter looks to me as if it would ultimately make it possible to drop the /usr directory entirely (once we've had a release or three in which it contains nothing but symlinks) - whereas the former means we'd have the extra four characters at the head of nearly every path to installed software forever, for no apparent benefit, and would also seem to mean we'd have to keep the symlinks in / around potentially forever, even after the transition has been complete for yonks. I'm not sure I'd support dropping /usr, but I don't think I can remember having ever run across (or come up with) any arguments against it which don't seem like they would also be arguments against doing this merge at all, so the fact that the merge is apparently being done in this direction has consistently puzzled me. Does keeping /usr have some kind of benefit in its own right which I'm not seeing, even for cases when it's on the root filesystem?
