So the idea of backing it by chmod with -c sounds great but we'd need an
option for when it was non-GNU, really it would need to autodetect and use
the legacy path.

Generally I don't like including alternate code paths, but this would
mainly be for recursive=yes and in that case we could have a caveat about
behavior on non-GNU systems if need be.
