[rsbac] About ACCESS_CONTROL and SUPERVISOR rights

[Javier J. Martínez Cabezón]

Thanks for your answers Amon. I think this part of the handbook that
explains the rc model is a bit confuse:

– ACCESS_CONTROL: Change normal (old) access rights to this type for
your administrated roles
– SUPERVISOR: Change these new special rights to this type for your
administrated roles.

Can  it be substitute by: ACCESS_CONTROL: Change none-security related
rsbac access rights to this type for your administrated roles.
-SUPERVISOR: Permits add or remove security rsbac related rights to
this type for your administrated roles.

At first I though MODIFY_PERMISSIONS_DATA and ACCESS_CONTROL were
redundant I was wrong seems.
