Would it make sense to label the data (resource) with a list of paths (names) that can be used to access it?

Therefore the data would be protected against being accessed via alternative arbitrary names. This may be a simple label to maintain and (possibly to) enforce, allowing path based confinement to protect a resource. This may allow for the benefits of pathname based confinement while avoiding some of its problems.

Obviously this would not protect against a pathname pointing to arbitrary data…


Just a thought.
