i think.... having a single hierarchy is fine *if* and only if it is
possible to overlay something similar to SE/Linux policy files -
enforced by the kernel *not* by userspace (sorry serge!) - such that
through those policy files any type of hierarchy be it single or multi
layer, recursive or in fact absolutely anything, may be emulated and
The fundamental problem is that sometimes you have types of controls that are
orthoginal to each other, and you either manage the two types of things in
separate hierarchies, or you end up with one hierarchy that is a permutation of
all the combinations of what would have been separate hierarchies.
