Care to explain why? I believe you may be confusing OS-level &#x27;capabilities&#x27; implementations (eg. Linux&#x27;s) with competing &#x27;RBAC&#x27; implementations (of which Linux has at least two or three). In fact if you remove the waffle the abstract-level model is the same, and IMHO is that a Wikipedia article should deal with the subject as a whole using the most abstract terminology possible... referencing implementations and their terminological preference is a secondary concern.
