I think you've stated what the problem is using Graph as the representation. In a filesystem a symlink entry is a pointer to the complete destination name, whereas when you're storing things as nodes you're seeing each step in the destination as a separate node (and you've lost the notation that "/p" maps to "/a/b/c/d" (or whatever)).

Little fuzzy, but I think you've gone a bit far afield trying to reimplement a filesystem. To do what you want (stipulated that I'm incautiously reading the problem) it almost seems to me that you want to have a list of links ordered from longest substitution to shortest and then walk that list of substitutions s{$cur_subst}{$cur_replacement} in that order.</handwavy>
