> {{FSDirectory}}'s path resolution currently uses a mixture of string & 
> byte[][]  conversions, back to string, back to byte[][] for {{INodesInPath}}. 
>  Internally all path component resolution should be byte[][]-based as the 
> precursor to instantiating an {{INodesInPath}} w/o the last 2 unnecessary 
> conversions.
