This is especially useful for the concept of principal mapping within Knox.
A user that authenticates as "foo" may be mapped to a principal of "bar".
Consequently, a script that logs in then accesses files within their home
directory should be able to do so relative to their home directory.
Without supporting the notion of "~" the user must know what their mapped
to principal is and hardcode file access based on that value.
Which may also change out from under them - or be different across clusters.
