I'm not sure I understand this issue in detail, but why would using
rmtree() on something you expect to be a symlink ever be a good idea?
It seems like if things are the way you expect them to be, it has no
benefit, but if they are different from what you expect, you might
blow away a ton of important data.
Maybe I am just confused.
