These are just random thoughts and I have no idea whether there is
anything useful in them.

We know what one of the paths to a volume root happens to be.  If we can
detect when a second path is being used, perhaps instead of returning
the vnode we already used, we lie and produce a new "local only" vnode
that is a symlink to the original mountpoint that was crossed.

This at least would provide a degree of consistency.  "cd .." would step
up to the right directory.

Like I said, just random thoughts.
