This shouldn't be so hard to obtain.

I mean we could simply introduce a new command "rename oldpath
newpath" that only works when both path share the same mount point.
This way the mv commands would keep the old "safe" semantic, while the
new command would protect the user to accidentally disclosure his data
to the world via the cloud.
